Workaround for Installing KB Article KB971092 successfully

In some cases there is an issue with installing the following update “Security Update for Microsoft Visual Studio 2008 Service Pack 1 (KB971092)”.  The workaround to properly install the update you must set the security on the files vsvars32.bat and vcvarsall.bat to allow the local Users group write permission on those files.  I am not sure why this is an issue but from reading other posts and such on the issue most of the affected people do not have vc++ installed.

They can be found in the following folders:


  • C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat
  • C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat


  • C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat
  • C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat
