Troubleshooting Duet client install errors

  • Article

When attempting to install the Duet client to user in an automated fashion, the install may fail with an error.  The error may seem cryptic, but we have a document on TechNet that can help explain what piece may have failed.  For instance here is a excerpt from a setup log that failed:

 

9/24/2009 : 8:47:28 AM : I:    Invoking Duet 1.5 SP3 Install
9/24/2009 : 8:47:28 AM : I:    Executing following command
C:\Duet\setup.exe ACCEPT_EULA=YES REBOOT=ReallySuppress READSERVICE_URL=https://contoso.com:8020/DuetReadService.asmx /l*v c:\duet_SetupLog.log /qb!-
9/24/2009 : 8:50:47 AM : I:    Unknown Error. Result = 2. Please Check Installer Log for more information
9/24/2009 : 8:50:47 AM : E:    InstallDuet    Duet Installation Failed - error code: 2
9/24/2009 : 8:50:47 AM : E:    InstallDuet    Duet Client Install validation failed
9/24/2009 : 8:50:47 AM : E:    install    Installation/verification failure, see detailed errors

 

If you navigate to technet.microsoft.com/en-us/library/cc983797.aspx you will see the following chart:

 

<snip>

/InstallPreReq (or any other install options) – Returns 0 on Success, non-zero values specify the stage at which installation failed.

  • UNSUPPORTED64BIT -1000

  • OFFICENOTINSTALLED 1

  • SQLINSTALLFAILURE 2

  • VSTOINSTALLFAILURE 4

  • DOTNETINSTALLFAILURE 8

  • OWC11INSTALLFAILURE 160

</snip>

 

From this you can see that error 2 indicates that there was a problem with the SQL client installation.  With this information, you can look at other setup logs to figure out why the SQL client failed to install.
