Removal tool to fix .NET Framework install failures

Articolo
04/08/2005

I wrote an application late last year that is designed to clean up computers that have problems getting the .NET Framework 1.0 or 1.1 to install correctly. I have been working on refining the tool for the past couple of months, working out some bugs, adding additional cleanup features, etc. The .NET Framework setup Product Support team has been using this cleanup tool for the past few months to help resolve many cases, and the internal Microsoft helpdesk has also started using it to solve internal cases where employees cannot get .NET Framework service packs or hotfixes to install correctly. I have also been sending this tool out to individuals who email me via my blog and ask for help resolving setup problems - most commonly this is because of issues installing .NET Framework service packs or hotfixes such as MS05-004.

Since I have been seeing really good success rates for using this cleanup tool and it has proven to speed up the process of resolving issues so customers can get the .NET Framework installed correctly and start using managed code on their computers, I decided to try to get a KB article written up with a copy of the tool that customers could download on their own without needing to contact me directly or call our PSS team. The KB publishing process can sometimes take a while with technical reviews and things like that, so in the meantime I am going to post a link to the tool here on my blog.

You can download the tool by visiting the .NET Framework Cleanup Tool User's Guide and using one of the download links listed there.

There are a couple of very important caveats that you should read before using this tool to cleanup .NET Framework bits on your machine :

You should try to perform a standard uninstall first. This tool is not designed as a replacement for uninstall, but rather as a last resort for cases where uninstall or repair did not succeed for unusual reasons.
This cleanup tool will delete shared files and registry keys used by other versions of the .NET Framework. So if you use it, be prepared to repair or reinstall any other versions of the .NET Framework that are on your computer to get them to work correctly afterwards

The tool itself has been fairly well tested, but I'm sure it is still not perfect. I'm still in the process of fixing bugs as I find them and adding features to make it more effective at cleaning up known issues and to make it more intelligent about identifying root causes so we can fix the underlying bugs in .NET Framework setup for future releases. As I update it, I will post updates to my blogs and update the copy of the tool located at the link above.

I hope this tool will be helpful in resolving problems installing the .NET Framework. Please let me know if you run into any issues while using the cleanup tool or if you are still unable to install the .NET Framework (or any service packs or hotfixes) after running it.

<update date="3/3/2009"> Added a link to the .NET Framework Cleanup Tool User's Guide , which contains the most up-to-date download location for this tool. <update>

You should consider using an extension for the EXE that at least defaults (both on the server and in clients) to a binary MIME type, so that if a user simply clicks on it they will be prompted to download it. You could use a real extension like .zip (and zipping the EXE would reduce size) or (if WinISP supports it, and I honestly don't know it if will) .bin (which typically defaults to "application/octet-stream" for unknown and/or unmapped extensions).

Mike - we are actually in the process of getting a version of this tool ready for the Whidbey .NET Framework also. There are a couple of fixes I need to make to fully enable this for all of the beta and community tech preview versions of the .NET Framework 2.0 that are out in the wild. Stay tuned, I'll post an update to my blog when I have something ready to try out.

Heath - thanks for the posting suggestions. I could've sworn I had tried to upload a ZIP file to the WinISP site and it failed in the past. But I just tried again and it worked. So I'm going to update the text of this blog item to reflect the new link.

Thanks for having a go. I ran this but still can't install .net 1.1 via dotnetfx.exe on xp pro. I have tried all other MS and your suggestions but to no avail. Looking at the MSI .log it fails at Registering System.EnterpriseServices.dll:

Hi Dave, we have gotten a lot of reports of .NET Framework installation errors where the failure occurs when trying to register System.EnterpriseServices.dll. Unfortunately we have not found a consistent root cause for this. In a lot of cases running my cleanup tool will help, but in many others it will not.

The tricky part here is that registering this DLL is the first time that the underlying CLR is used to run managed code, and so if any part of the CLR is not working then this action will fail. But there are many possible causes for the CLR to not be working when it is being installed.

I am working on a blog post describing how to gather debugging information from this action during setup to aid us in figuring out the root cause. I will post a link to it once I get my steps tested and posted on my blog....sorry for the delay.

Hi,

I'm also having the same error which Dmitri has while installing .net framework 2 beta 2 :

Error 25015.Failed to install assembly
'C:WindowsMicrosoft.NETFrameworkv2.0.50215Microsoft.VisualBasic.Vsa.dll' because of system error: Access is denied.

I've already tried both things that astebner suggested to do, but still doesn't work. In File Monitor, I didn't find any "ACCESS DENIED" result. I found only "PATH NOT FOUND" results as an error message, it's said that some dll not found in C:I386.

Any idea?

Thanks

Hi Fei,

First of all, I would suggest making sure that you have disabled any antivirus or anti-spyware applications (temporarily of course) during the course of setup. Sometimes those can interfere with installation and cause access denied errors. However, I would definitely expect to see a message in FileMon for any access denied error, so that is odd.

Do you see a pop-up dialog for this 25015 error? If so, can you try to use the tool gacutil.exe and manually install the assembly to the GAC while that error is on-screen and see if it gives any additional error information. You will need to do the following to try this:

1. Install the .NET Framework 2.0 beta 2 and .NET Framework 2.0 SDK beta 2 on a separate machine (you can get them at http://lab.msdn.microsoft.com/vs2005/downloads/netframework/default.aspx)

2. Copy gacutil.exe from %programfiles%Microsoft.NETSDKv2.0bin to the other machine where this failure is happening

3. At the point of failure, run gacutil /i C:WindowsMicrosoft.NETFrameworkv2.0.50215Microsoft.VisualBasic.Vsa.dll and let me know what the output is

Hopefully this helps...

Many thanks for your detailed reply to my original post of June 17. However, I'm pleased to report that after running assorted clean-up & registry repair utilities, .NET Framework 2.0 re-installed without problem, swiftly followed by VS2005 Team beta 2.

Thank you for your work in creating this clean up utility.
After an OS repair from the restore cd I could not reinstall Net Framework.
With the help of your utility, installation went smoothly.

Aaron:

I was just cleaning up my \desktop and noticed your removal utility lingering thereupon. (I had put it to use on April 30 ... exactly 3 months ago ... so it appears.)

Alas, I owe you very special thanks for finally rectifying a maddening .net botched install ... one which caused me continuous grief at the hands of my antivirus software -- which persistently admonished me for an out-of-date windowsupdate status. (Windowsupdate was unable to apply .net patches ... because of the botched install.)

In any case, I don't know who you are ... but you have my vote for software philanthropist of the year. May good things come to you in abundance.

Thank you,
David

I need to reinstall Team System Server but a message says 'setup has detected existing Team Foundation databases on this machine and this operation cannot be continued. Please refer to the accompanying documentation on how to reuse this machine.'

Aaron, Just wanted to let you know I tried the workaround you recommended based on my prior post. This work around solved the problem and I was able to successfully install the 2.0 .NET framework. Sorry I was not more diligent about looking at the other content in your blog.

George - I'm glad that the workaround was successful. It is hard to find all of the random comments I've posted, so there's no need to say sorry. I'm going to try to pull some stuff together into a parent post that serves as kind of a troubleshooting guide with a bunch of sub-links to my other posts, but I just need to find time to get it all typed up :-)

Tpham - I received your email and sent you the following set of steps, which you indicated resolved your issue (I'm posting them here for any others who happen to read my blog):

1. Uninstall the Data Tier
2. Launch SQL Management Studio
3. Delete all of the following databases if they exist:
BisDB
BisDWDB
CurrituckDB
ELeadDB
Psshared
VSTEAMSCC
VSTEAMSCCAdmin
4. Re-run Data Tier setup

If you are performing a single server setup, you will need to do all of the above plus the following additional step:

5. Uninstall ADAM (this can be done before or after uninstalling the Data Tier)

Hi tpham
Regarding the Team System Server installation , you should just go to the SQL server and delete all the databases that you dont know , make sure to leave the Report & ReportServer databases , otherwise you need to reinstall the SQL 2005 report service

Cheers and good luck ,

Hi Aaron -

Thanks for all your efforts on this blog, I found it extremely useful, and came close to solving my .NET Framework problems, but fell shy of the solution. I am guessing, given your new job, that you will know the answer handily.

After much effort, I found I needed to use your clean-up tool to remove 1.0 and 1.1. The good news is I can easily re-install 1.1, but the program that asks for the original source CD to install 1.0 would not correctly recognize my MCE 2005 CD.

How can I re-install .NET Framework 1.0 on an MCE 2005 machine?! Are there manual steps listed somewhere, or a way to force msiexec to recognize the original install CD/netfx.cab?

Thanks,
Ron

Hi Ron - .NET Framework 1.0 is installed as part of the operating system on Windows XP Media Center Edition (and Tablet PC edition). Therefore you cannot re-install it by simply running the dotnetfx.exe package or any msiexec command lines.

The instructions for repairing the .NET Framework 1.0 that comes as part of the OS on MCE and Tablet are a little bit complicated, so I posted a separate blog item about this, you can find it at http://blogs.msdn.com/astebner/archive/2005/09/01/459631.aspx.

I know they are kinda convoluted, so if you have any issues please don't hesitate to contact me at aaronste (at) microsoft (dot) com and I will do my best to assist you....

Hi there

Where would I find the program for the NET FRAMEWORK INSTALLER on the windows CD. My reason is that I have two different versions of xp pro....one has problems installing but net framework programme is good and the other installs windows perfectly but not the net framework.....I wish to combine best of both onto one cd.

hope this makes sense.

Hi Dan - If you have a CD with XP Pro with SP1 integrated, you can find the .NET Framework 1.0 in the dotnetfx folder in the root of the CD. If you have a CD with XP Pro with SP2 integrated, you can find the .NET Framework 1.1 and 1.1 SP1 in the dotnetfx folder in the root of the CD.

Also, you can download the .NET Framework from the web as a standalone package. Check out the links at http://msdn.microsoft.com/netframework/downloads/updates/default.aspx.

Hi McKirahan - I'm sorry for the hassle here. The first important thing to mention is that the .NET Framework 1.0, 1.1 and 2.0 are designed to be side-by-side, so you can definitely have all 3 versions installed at the same time.

I think the best route to go now that you have tried to remove 1.0 and 1.1 is to use the instructions that I posted at http://blogs.msdn.com/astebner/archive/2005/10/11/479928.aspx to clean and reinstall both 1.0 and 1.1, and then install 2.0 and the WebDev and SQL 2005 Express editions.

Please contact me at http://blogs.msdn.com/astebner/contact.aspx if you run into any issues getting these steps to work...

I don't know if you got this submit:

Dear Aaron,

HUGE THANKS! I have to praise (big praise) you SO much for your gift of that cleanup tool!!! I went through all the steps to try to find out why the MS update failed in two new machines I was installing for husband/self. I had started getting errors like those noted in some of your blog pages, and that type of thing is a major warning to "cleanup."

I tried walking through the long drawn out fix offered at the MS site (having drilled through many URLS until I got there) and THEN I got stuck on the fix because files/dirs they said to delete would not delete!

Ultimately, I couldn't figure out why a security download would NOT install and I wanted that security. I was JUST about to give up after 3 hours into this, when I found YOUR page and downloaded this cleanup tool. Long story short, NOTHING worked until I used your cleanup tool.

For those who might be stuck like I was... Here were my steps to overcoming this "painful" problem (many thanks to Aaron's help!):

Went here for the dotnetfx.exe file:
http://www.microsoft.com/downloads/details.aspx?FamilyID=262d25e3-f589-4842-8157-034d1e7cf3a3&DisplayLang=en

1. Downloaded/extracted the dotnetfx.exe files into a dotnet directory/folder on drive C like this (thanks to Aaron). StartRun then typed in: dotnetfx.exe /t:c:dotnet /c

2. I used Aaron's "Cleanup tool" dotnetfx_cleanup_tool.zip by simply opening the zip and running cleanup_tool.exe This worked like a charm.

3. Then ... to install .NET Framework 1.1 I went to my "dotnet" directory and double clicked: netfx.msi

PARTIAL VICTORY!

NOTE: I went to the following to download...
http://www.microsoft.com/downloads/details.aspx?FamilyID=8ec6fb8a-29eb-49cf-9dbc-1a0dc2273ff9&DisplayLang=en

Security Update file: NDP1.1sp1-KB886903-X86.exe

Microsoft's notes:
"ASP.NET Security Update for Microsoft .NET Framework 1.1 Service Pack 1"

I attempted to install NDP1.1sp1-KB886903-X86.exe
and got this message:

"COULD NOT INSTALL NDP1.1sp1-KB886903-X86.exe with this error message:
"Info 9006. This patch cannot be installed because it requires Microsoft .NET Framework 1.1 Service Pack 1(SP1). No Microsoft .NET Framework 1.1 SP can be detected on this computer. Please see http://support.microsoft.com/?kbid=886903 for more details."

SO...I went back to the MS Windows update site...

4. I still had KB886903 update to install. I did so...and Bingo.

Done.

Aaron, I wouldn't have gotten there without your help. This type of problem is COMPLETELY obnoxious and a time waster. Even so...I would not have been able to resolve this without your hard work and I thank you!

I've tried setting the security settings as Derek suggests, and running FileMon doesn't return an error.

From dd_netfx20:
03/11/06 10:27:29 DDSet_Error: Failed to install assembly C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Microsoft.VisualBasic.Vsa.dll. IAssemblyCache->InstallAssembly() returned -2147024875.

FileMon notes End Of File on VisualBasic.Vsa.dll but no failures.

Can anybody suggest anything else to help?

Thanks,
AndyC

Guys,

I've solved this problem. I had to remove all my framework versions and then in my Windows/Assembly directory I had some existing subdirectories that needed clearing out, including GAC_32 and GAC_MSIL.

I'm not sure what happened along the way to cause this problem, as I had hoped to run different framework versions alongside each other. But thanks to Aaron, using your manual uninstall process got everything working again.

Thanks,
AndyC

Hi,

We have one PC that gets the following error in the Microsoft CRM 3.0 Outlook Client installer, and can't get past the system requirements phase of the installation:

"Microsoft CRM Client for Outlook Setup User Input File or assembly name 9o3db28v.dll, or one of its dependencies, was not found."

(the file name is random and changes on every installation attempt). Any suggestions? Do you think removing the .NET Framework might help? The user is a local administrator and has rights to the user and system Temp folders.

Thanks! I had an XP machine in .NET confused state for some time now (can't install, can't un-install...) and this fixed it.

I used the uninstaller "ttool.exe", but all it did was remove my newest version of .net framework 2.0. I'm looking for a tool to remove the beta 2 versions. I HAVE BEEN POINTED TO MICROSOFT ALREADY... I do not have any uninstallers. I have the installer that links to a dead end, therefore, I will never be able to get the uninstaller back. Is there anyone who has a list of the registers and folders so I can remove them myself, or is there a better program than the two similar ones from Microsoft. The one on their page gives me error message saying I might not have access to them if I am not an Administrator, but of course, I am... anyone who has the best way to remove these programs, can you think of a way without hurting my .net Framework 1.1 or 2003 registered version?

Hi Aaron, the installer is part of CRM. The complete path we're using is this:

msiexec.exe /i "\SERVER1ClientAppsMSCRMDesktopClientlightclient.msi" CONFIG="\SERVER1ClientAppsMSCRMDesktopClientdefault_client_config.xml"

...however, copying the folder to the workstation and installing from there yields the same result.

Again, let me reitterate what I just wrote... I DO NOT HAVE THE UNINSTALLERS.... I've also tried 2 versions of Microsoft's uninstaller on that page and the one on one of this website's pages. It says I do not have rights or something like that because I am not an Administrator. But I am! I own the computer. I don't have uninstallers, but I still have registers and assemblies and some hidden files in directories. I can remove the 8.0 version in program files, but there is much more to remove in sys32 in %windir% etc... I need to do this manually it looks like. ADD/REMOVE programs is out of the question. I have a registered version of 2003 in there, so I don't want to hurt it. Any suggestions besides the obvious?

I have the June version of SQL Server to install, but I need to remove the betas first. I don't want to do it by myself so that I don't delete needed files or registers of my 7.1 version. Some is obvious, some isn't, some is hidden. Any manual suggestions? Or if there's a 3rd BRAND NEW PROGRAM, NEW AS OF released today or anytime hereafter...any help beyond what is on main microsoft website is gratefully appreciated... Thanks again!

Hi Jmonkey - I am not sure I understand your comment saying "I do not have the uninstallers" - does this mean that none of the beta VS 2005 versions show up in Add/Remove Programs at all? If that is the case for you, can you please try to Can you please try to use the instructions listed at http://msdn.microsoft.com/vstudio/support/uninstall/default.aspx to determine a list of the exact products you need to uninstall, and then use the steps listed at http://blogs.msdn.com/astebner/archive/2005/10/30/487096.aspx to locate and manually remove each of them. Hopefully this helps.

I would also be curious to know how your machine got into the state it is in. I haven't ever heard of a case where every entry disappeared from Add/Remove Programs like that (in the case of VS 2005, it installs somewhere between 5-10 different Add/Remove entries). Have you done anything like a system restore recently that might explain the things disappearing from Add/Remove Programs like that?

Hi Jmonkey - I am sorry, it looks like you posted your last question as I was typing my previous reply, so I didn't see it at the time. The .NET Framework 2.0 is a prerequisite for Visual Studio 2005, so you will have to have it installed if you want to install VS 2005. You will need to make sure you are installing the final release of VS 2005 and not one of the old beta versions though, because the final release of the .NET Framework 2.0 will only work with the final release of VS 2005.

You know why I ask...I have cd's sent to me from Microsoft with SQL 2005. And isn't SQL 2005 a prereq to install Visual Studio 2005...? I try installing it, it's a June 2005 Community Edition Release, and it tells me this reason...it goes first, followed by Visual Studio, then the framework. I know by Visual Studio 2003 Windows SP2 and framework 1.1 and a few other things were first. Maybe I read the page wrong...

Hi Aaron.
First af all, excusme for my bad english.
My problem is:
I had the Microsoft .NET Framework 1.1 and the Microsoft .NET Framework 1.1 Hotfix (KB886903) installed on my Win XP Pro SP2.
I uninstalled them in a wrong way: First, in Add/remove Programs, I unistalled the Hotfix, but WITHOUT restarting the machine, and then I uninstalled the Microsoft .NET Framework 1.1.
This was fatal.
Now, each time I start Wondows tow little error windows appears. I accept the two windows and the Win XP works.
I tried to uninstall again with Add/remove Programs: Dont work.
I tried to uninstall and repair with the Installer: Dont work.
So, I can not unistall, repair or reinstall the Microsoft .NET Framework 1.1

I want to unistall the Microsoft .NET Framework 1.1.
What can I do?
Can I try your tool?

Thanks in advance.
Luis.

Hi Rican - I am not sure what the file "hpqasset" is, but it is not a part of the .NET Framework. I think that the error is just being reported by the .NET Framework because the other program is a .NET application. I would suggest trying to find what program the file "hpqasset" is a part of and then repairing that program.

Thanx Aaron... I looked over your suggestions and decided to do it my way - brute force and ignorance - simply because I was quite fedup with trying any and every workaround I came across and I wanted to have the option to uninstall in the future.

I cleand up with your tool and also the windows cleanup utility.

I identified anything that had to do with .net and vs2003 and manually deleted - from files, folders all the way to reg entries.

Ran Registry Mechanic to scrub the registry.

Downloaded .net 1.1, the sp1 and hotfix 866903 and installed in that order ... it worked... tried uninstalling and that worked too.

Interesting observation: before all this, add/remove was reporting .net and hotfix at 249MB each, now with the new install they both come in at under 24MB each... where the previous bloat came from is still a mystery.

A recent Windows Update failure (Error number 0x80190193) encountered when applying patch kb886903 to .NET 1.1 SP1 was completely resolved and eliminated by temporarily shutting down an old version of the ZoneAlarm firewall. (A dozen other, more complicated fixes had no effect.) YMMV HTH

Many thanks. The removal tool solved a very longstanding problem of being unable to install security update for .Net Framework 1.1. Interestingly, the tool claimed to have failed. And Microsoft Update was not showing me .Net Framework 1.1 as an option. So the tool must have left something behind. But installing .Net framework manually, then its SP1 allowed Microsoft Update to show me the security update to 1.1SP1, which installed successfully (though did not actually require downloading, interestingly enough, indicating something else missed by the tool. But the removal tool is great, even so!! Many thanks again Mr Stebner...

It gave error message: Error Starting Program The CLEAN.EXE file is linked to missing SHELL32.DLL:SHGetFolderPathW I tried running the program from the Windows Temp folder and Windows System folder where Shell32.dll is located, but still won't work. Any thoughts on what's wrong? Thanks.

Hi Mikey3 - This error means that the function ShGetFolderPath doesn't exist in the file shell32.dll on your system. The documentation for that function says that it requires at least version 5.0 of shell32.dll. I have written the code to delay load that DLL so that if a lower version were present, it should not cause any problems. However, there might be a bug in that code somewhere. Can you check on your system and see what version you have of shell32.dll on your system? Also, would it be possible for you to contact me at Aaron.Stebner (at) microsoft (dot) com so I could try to send you a private build to test out some options for fixing this issue? I haven't been able to find a system that I can reproduce this issue on so far.

The new cleanup tool ran successfully, but also included an error message at the beginning of the log: ERROR GetProcAddress failed for 'SHGetFolderPath' with error code 127 - The specified procedure could not be found. The shell32.dll is version 4.72.3812.600, and from FileSnoop it doesn't have the Export function "SHGetFolderPathW". Does the lack of that function affect any cleanup routines in your cleanup tool? Would anything be left on the PC because of it? I'm not planning to reinstall .NET Framework on this PC again because Microsoft doesn't offer any patches for it on Win98SE anymore - one less security problem to worry about. So, I can't tell you if a reinstall would work out well or not.
Anonymous
July 22, 2007
Hi Mikey3 - That error is expected if you have a version of shell32.dll less than 5.0.0.0. The cleanup tool tries to use shell32.dll to locate the Program Files directory on your computer, and if it fails to find the function that it needs, it will look up the location in the registry as a back-up. So, even with that error, the tool would have worked fine for you.

Hi Aaron. First let me add my thanks for this tool. I was in a hopeless mess trying to uninstall .NET to get rid of the dreadful 982366 upgrade problem. Your tool seems to have stopped the latter, and very nearly tidied up my installation. I just have one question - I still have Microsoft .NET Framework 1.1 Hotfix (KB886903) showing in Add Or Remove Programs. It will not uninstall ("The upgrade patch cannot be installed because the program to be upgraded may be missing . . ."), and it does not show up in Windows Install Cleanup. I really don't need .NET 1.1 at all any more, and I'd like to stop going round the endless install-uninstall loop and just get .NET2 installed and get on with my life, but it would be nice to get everything tidy and get this oddball hotfix out of the AORP list. Any suggestions?
Anonymous
August 27, 2007
Hi DaveMidgley - I'm glad that the cleanup tool was helpful for you. It sounds like there are a couple of additional registry entries left behind on your system that cause the KB886903 item to appear in Add/Remove Programs even though it has already been uninstalled. You can go and manually delete those - they will be located under HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionUninstall. Also, if you don't mind, could you please report back the exact names of the keys/values you had to remove so that I can update the cleanup tool to remove those in the future as well?

If that doesn't help, and if running the cleanup tool listed at the top of this blog post also doesn't help, then I'd suggest posting a question on the MSDN Forums at http://forums.microsoft.com to see if someone there can help suggest any other workarounds.

Hi Pravesh - I'm sorry for the hassle this issue is causing for you. You can use the steps listed at http://blogs.msdn.com/astebner/archive/2005/03/29/403575.aspx to make the .NET Framework 1.1 setup create a verbose log. Then you can zip and send me the log at Aaron.Stebner (at) microsoft (dot) com and I can try to take a look and see if I can figure anything out about the root cause of this 1935 error.

Uninstaller didn't work. Reinstall didn't work. This little tool did the trick. Thank you very much and Merry Christmas :) Preston

Hi Cnsrvative - Do you have the full text of the error message that you're running into in this scenario? Error 25015 is a catch-all for any type of error that the installer doesn't specifically recognize (in coding terms, it is the default case at the end of a big switch statement), so there are a lot of possible causes. Usually, error code 25015 will be followed by some more specific information about the cause of the error. The name of the file being installed doesn't usually help narrow down the cause, but since it mentions System.EnterpriseServices.dll in this case, you may want to see if either of these workarounds helps for you: http://blogs.msdn.com/astebner/archive/2006/01/08/510677.aspx http://blogs.msdn.com/astebner/archive/2006/11/25/disabling-services-with-msconfig-to-work-around-setup-failures.aspx If you've already run the cleanup tool, there's no need to also try the steps in that other blog post. Those steps are the same as the ones run behind the scenes by the cleanup tool. Regarding the support question, my understanding is that you can use the Developer Tools support option like you would for Visual Studio, and that installation issues do not require payment. I'm not sure if there have been any policy changes since I heard about that though. Hopefully this helps.

I got no sense at all fro, Mircrosoft Help & Support. Then I found this tool, and everything fell into place. Thank you very much for your expertise. Bill

I have tried EVERYTHING to be able to Install .NET Framework 2.0. Uninstall / reinstall, clean out all versions of .NET, etc etc etc you get the idea. I am still getting the error System.EnterpriseServices.dll can not be found when installing. I've checked the directory and before the install the file doesn't exist. During the install it creates the file, and after it fails and I hit finish it deletes it again. I disabled McAfee as well. Any more ideas here? Please email me for faster communication. I am in a corporate environment and even our IT people are stuck and I need this fixed ASAP.

Hi Vaximily - I'm sorry for the hassles that this issue is causing for you. It sounds like you've tried most of the steps that I know of for troubleshooting .NET Framework installation issues. There are a couple of other things that are specific to issues with System.EnterpriseServices.dll that you may want to try as well: http://blogs.msdn.com/astebner/archive/2005/07/27/444085.aspx http://blogs.msdn.com/astebner/archive/2005/07/24/442747.aspx http://blogs.msdn.com/astebner/archive/2006/01/08/510677.aspx Also, if you haven't already tried it, you may want to try disabling services with MSConfig as well using the steps at http://blogs.msdn.com/astebner/archive/2006/11/25/disabling-services-with-msconfig-to-work-around-setup-failures.aspx. If none of the above work, then I think you will need to contact Microsoft Technical Support for more in-depth troubleshooting assistance. There is contact information at http://support.microsoft.com and you should be entitled to a free support case for setup-related issues such as this. Hopefully this helps.

Hi Beemf - Since you're running a 64-bit OS, could you also check and see if you have a v3.0 key at HKEY_LOCAL_MACHINEWOW6432NodeSOFTWAREMicrosoftNET Framework SetupNDPv3.0? If you're getting an error saying a later version of the .NET Framework 3.0 is already installed, that typically means there is something incorrect in the registry somewhere.

Hi, I check under LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftNET Framework SetupNDPv3.0 and v3.0 was there. I just delete v3.0 folder and the installation of .net framework 3 sp1 was successful. Is that ok? Just delete all content under v3. I was doing that on copy of virtual server and dont want to damage production server. Thanks for all the help Astebner.
Anonymous
May 27, 2008
Hi Beemf - .NET Framework 3.0 and 3.5 setup use registry values in locations like that to determine if a newer version of the product is already on the system, so it is probably OK to remove those values in order to unblock installation if you are getting that error and you are sure you don't already have a newer version installed. Just to be sure though, can you list exactly what you have in your registry at that location so I can take a quick look?

Oh dear me, I think ive messed up using this thing. I couldnt install framework 3.5, so i used your tool and wiped all framework installation of my pc. Since im on vista premium 64x its not so happy about not having framework 3.0 installed. The big problem is when i try to install framework 3.0, it gives me an error saying I need to "activate or deactivate windows-functions" in the controlpanel to install or configure microsoft.net framework 3.0 x 64. (basically translated from danish to english) The real problem is that there doesnt seem to be anything to activate or deactivate in "windows-functions" under programms and functions, where you are supposed to be able to turn on and off windows-functions such as allowing the framework 3.0 x 64 to be installed/configured :S If you are unsure what menu im talking about, here is a screen: http://img.photobucket.com/albums/v365/RN1807/problemo.jpg

Aaron hi, I got a problem 0x643 while installing the .NET 3.5 SP1 via Automatic Updates. I went through all the loops and got here. After running your tool several times I was not able to install .net 1 sp3 and .net 1.1 sp1, but all the other .net packages excluding 3.5 sp1. I saw your other article about 1603, but I guess I need to clear this problem first. I am running XP Pro SP3. I think all my problems started after I cloned my old hard drive to a new one, if that is any help. Any help will be greatly appreciated! TIA!

Hi Kclewis - The System.TypeLoadException that you are encountering typically means that there are some old .NET Framework 3.0 bits left behind somewhere on your system that are interfering with .NET Framework 3.0 setup. I'd suggest trying to use the steps listed at http://blogs.msdn.com/astebner/archive/2008/03/07/8108332.aspx to remove all versions of the .NET Framework from your system, then proceed to install the .NET Framework 3.5 SP1 (this will install 2.0 SP2 and 3.0 SP2 for you behind the scenes).

Hi Vvkalkundri - First of all, the cleanup tool is not designed as a replacement for the standard .NET Framework uninstall process. I would suggest automating the standard uninstall for your test scenarios so you will more closely match what a customer will actually do on their system. I have posted other items on my blog about how to automate the install and uninstall of various versions of the .NET Framework - you should be able to search my blog archive to find them. That being said, I don't know of any reason why the cleanup tool would hang. Do you have log files from the cleanup tool when it is hanging that you could post on a file server so I can take a look at?

All of the cases I've run into in the past of error code 0x800131700 have been resolved by fully uninstalling the .NET Framework using the normal uninstall process + the cleanup tool and then re-installing. You may want to try to contact Microsoft technical support for more in-depth troubleshooting assistance. You can find their contact information at http://support.microsoft.com.

Hello. For days now I have been trying to install .net framework 3.5. It all started when I tried to run and install a new porgram to my VPS windows server 2003 enterprise X64 edition sp2. When I tried to install the program I received a message stating .net framework 3.5 is needed. Well, I thought no problem I'll go to microsoft and download the program. This is when all my problems began. I went to check to see what version of .net framework I had and it was 2.0 SP2. I went to install 3.5 and it stopped and rolled back leaving 2.0 SP2 in its tracks, but no 3.5. I went to add and remove 2.0 and then tried to load 3.5 again and the same things happened 2.0 reappeared, but no 3.5. I then followed some of the steps and methods listed on this forum, other forums, and at the microsoft website. Needless to say thing went from bad to worse. I no longer can load any level of .net frameword and no version is available on the server. I went from partial loading with an error due to UIAutomationCore.dll failure, and 'The windows Installer could not be accessed error 1603' and the now an error 1719 relating again to the windows installer. Any recommendations would be greatly appreciated. Thank you. Jeff

The .NET Framework 2.0 SP2 installation is failing due to this error: MSI (s) (44:DC) [21:58:15:084]: Custom Action Server rejected - Wrong Context I'd suggest trying the workaround listed at blogs.msdn.com/.../10165211.aspx to solve this issue. The .NET Framework 3.0 SP2 installation is failing due to a different error: Error 1310. Error writing to file: c:WINDOWSSysWOW64UIAutomationCore.dll. System error 0. Verify that you have access to that directory. This type of error is usually caused by a file or directory permission problem on the computer. The steps at blogs.msdn.com/.../solving-setup-errors-by-using-the-subinacl-tool-to-repair-file-and-registry-permissions.aspx might help solve this problem. Alternatively, you could try to manually update the permissions on the c:windowssyswow64 folder on your computer - you will need to make sure that the local system account and the Administrators group have full control over this folder in order for .NET Framework setup to succeed.

Hi.Ive had this "Code 643" error ever since i tried to install the .NET Framework. I know your program has helped countless amounts of people but unfortunately for me, i am not a skilled computer user. Well i read and clicked the link to the download of your program but i do not know which software or application to run it with. I would appreciate your help so much. Thank You!.

Hi Ferguson - Are you getting code 643 when you try to install the .NET Framework? If so, which version of the .NET Framework? Would it be possible for you to use the tool described at blogs.msdn.com/.../6458047.aspx to collect all of your .NET Framework setup log files, then upload the file named %temp%vslogs.cab that this tool will create to a file server (such as http://skydrive.live.com), then reply back here and provide a link I can use to download your log files and take a closer look? To run the cleanup tool, all you need to do is save the zip file to your desktop, then open the zip file and run the .exe file named cleanup_tool.exe that is inside of the zip file by double-clicking on it.

Hi Ferguson - I see one log file named dd_clwireg.txt on your SkyDrive site, but I don't see the full vslogs.cab file that contains all of your setup log files. Can you please upload that file as well?

Aaron! A little problem to solve.. i tried using your tool but two updates failed to disinstall. Now (i think) updates fail to install because they are still on the system. Updates are: KB960043 KB963707 Thanks in advance for the help!

Hi Lolek - Can you please provide more details about the problem you are having? For example, do you have a .NET Framework installation issue that is preventing you from being able to play these games?

Hello Aaron - Got a BSOD while trying to install driver software for Lexmark Pro905 inkject printer. The BSOD did not show any driver error. Prtr installation failed. I copied down the STOP information. I did not send the info to MS as I thought no one would be looking at old XP BSOD data. There are apparently two WER files still on my computer. I also thought this might be related to the fact that I have not been able to install the .Net Framework 1.1 Service Pack 1 Update. I looked at this link: support.microsoft.com/.../922377 a decided to try and fix the problem. I first created a restore point and backed up the registry. I tried following the steps for .Net Framework removal (Method 1) from the link above but could not complete it. I got down to step 7 but could not remove the Microsoft Framework folder (apparently either not enough disk space or a clr.dll was in use). Method 2 suggests your tool. I would like to try this but want to check to see what other additional problems I might encounter. The following list shows the currently installed programs and updates related to this .NET Framework issue:

Microsoft .NET Framework 1.0 Hotfix (KB2572066)
Microsoft .NET Framework 2.0 Service Pack 2 plus subs below it.
Miscrosoft .NET Framework 3.0 Sercive Pack 2 + subs below it.
Microsoft .NET Framework 3.5 SP1+ subs below it.
Microsoft .NET Framework 4 Client Profile + six Security Updates for Microsoft .NET Framework 4 Client Profiles listing six different KB's. I have a feeling I am going to have to uninstall all of .NET Framework area and start over. I am running Windows XP Media Center edition on a Dell Inspiron 6400 (E1500). Would you please provide your estimate on what I will have to do as well as any suggestions on what precautions and or other steps I should take to make the task(s) easier. Thanks in advance.

Aaron, Thank you for your help. I still had to do a lot more reading but your explanations in this and other posts helped me understand what I needed to know to get the problem fixed. One of the most helpful tools was the Netfx Setup Verifier. The program along with readme file helped me understand what was supposed to be loaded and whether or not it was loaded correctly. Mike

After running the cleanup tool several versions of .net framework are still shown in the programs list. When I go to uninstall I get a message saying that this can't be done because the programs are not installed. Upon attempting a reinstall the installation fails. The versions are 3.5 and 1.1 sp1. Has anyone reported this?

McAfee flags your tool. What gives

Hi Ted - I'm not sure why that would happen. The files that I uploaded are clean. Does McAfee have a mechanism to let you report false positives to them so they can update their signatures?

  Hi Paul ing - Can you please try to use the steps listed at https://blogs.msdn.microsoft.com/astebner/2005/03/29/help-me-help-you-if-you-have-setup-bugs/ to create a verbose log file from this failing install and upload the logs to a file server such as http://onedrive.live.com? If so, I can download your logs and see if I can narrow down the root cause of that error any further.

Absolutely no help for me in my attempt to install net Framework 4.5.2 on my Windows 7 -64 machine so that I can complete my inatll of Turbotax

  Hi Scott Papenfus - Here are a few repair ideas that you can try:1. Install the latest version of the .NET Framework (version 4.6.2 from https://www.microsoft.com/en-us/download/details.aspx?id=53344)2. Install the latest Windows service pack and updates if you haven’t yet.3. Try to run the System Update Readiness Tool from http://support.microsoft.com/kb/947821.4. Try to repair the files that are a part of your OS by using the steps listed at http://blogs.msdn.com/astebner/archive/2007/03/26/how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx.If none of the above help, then we will likely need feedback from Intuit / TurboTax about how to diagnose exactly what their installer thinks is wrong with a PC when it shows that error message.

i need help the C:\Windows\Microsoft.NET\Framework\v2.0.50727\installutil.exe file pops up ones in a while how do i fix this

  Hi Oresowy - This type of error usually happens when an application is trying to run installutil.exe and is most often an issue with the application (as opposed to being a problem with the .NET Framework). You can use a tool like Process Monitor (https://docs.microsoft.com/en-us/sysinternals/downloads/procmon) to narrow down which application is running installutil.exe and causing that pop-up to appear.
