Installing .Net 4.0 as part of VS2010 deployment to x64-bit Windows7 is failing sporadically with "Signature verification for file SetupUtility.exe failed" error in log.
Install succeeds sometimes if retried (using the same exact source file), however, it is not clear what exactly gets changed on a system. Behavior is easily reproduced with antivirus disabled on a system with UAC off.
The issue is blocking reliable admin deployment of VS2010 installations.
Is there a way to disable signature verification via command line switches?
Is there a known procedure or a hotfix to fix this type of failures?
