Biztalk Healt Monitor 5.0 update without internet access

Biztalk healt monitor (BHM) give guidance how to update when no internet access from the location where BHM is running.

Instruction is given like this (C:\Program Files (x86)\BizTalkHealthMonitor\BHM_self_update.mht):

"
How can you update BHM if the machine running it is NOT connected to Internet?
The process is also easy and fast:

• Copy both files ‘ChkBHMRep.exe’ and ‘Microsoft.WindowsAzure.Storage.dll’ from the BHM folder on a machine connected to the Net
• On the connected machine run ChkBHMRep.exe w/o specific params to download quickly the updated BHM components in a subfolder named “\Updated”
• Copy the downloaded components from this subfolder to the installed BHM folder on the machine running BHM
• Re-register the BHM snap-in on the machine running BHM (mandatory if ‘mbvsnapin.dll’ or MYHC.dll belongs to the updated components) :
• Open an Admin cmd in your Microsoft.Net folder (C:\Windows\Microsoft.NET\Framework\v4.0.30319)
  • Run this command: installutil “C:\Program Files (x86)\BizTalkHealthMonitor\mbvsnapin.dll” (if BHM was installed in its default folder)
    "

that does not work at all in BHM 5.0. I have not tested does that still work with BHM 4.5 but that worked well at least in earlier.

first error what it gives is like below:
"---------------------------

Error

Cannot check the BHM updates. Be sure that BHMCollect.exe is in the same folder than ChkBHMRep.exe

OK

"
After copying BHMCollect.exe and couple of dlls to same folder it gives this kind of error:
"
Unhandled Exception: System.Security.SecurityException: Requested registry access is not allowed.
at System.ThrowHelper.ThrowSecurityException(ExceptionResource resource)
at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable)
at Microsoft.BizTalk.BHMSnapin.BHMRepUpd.Main(String[] args)
"

So my question is is there updated instuction available about this?
