I am running Windows Server 2012 as my desktop OS and need to install WIF 3.51 for some old 3.51 apps I need to build.
Downloaded http://download.microsoft.com/download/D/7/2/D72FD747-69B6-40B7-875B-C2B40A6B2BDD/Windows6.1-KB974405-x64.msu and tried to install but it fails with:
"Installer encountered an error: 0x80096002. The certificate for the signer of the message is invalid or not found."
How can I install WIF 3.51 on Windows Server 2012 (Yes, I understand that WIF is built into .NET 4.5 but this for .NET 3.51 apps not 4.5)?
