Office 2013 and .NET patches installation blocked by system policy


  • I am currently working on applying patches via WSUS in my organization.  My clients are able to successfully pull the required updates from my WSUS server and can successfully install Windows OS-specific patches.  However, when trying to install patches related to Office 2013 or .NET Framework, the install fails immediately.  I downloaded one of the .NET patches and tried to install it manually as an administrator.  It failed with the error that the message "Installation is forbidden by system policy."  I have done some research and was directed to look at the policy for Windows Installer.  This policy is not set, so I know it is not this policy.  Any help you can provide is appreciated.

  • Solved the problem.  Found that it was a GPO under Windows Components / Windows Installer.  The policy was "Prohibit patching" and it was enabled.
