CRM 2011: Issue Installing Windows Identity Foundation

While installing Windows Identity Foundation as a Pre-Requisite for CRM 2011 on Windows Server 2012, I was getting this strange error:

"The certificate for the signer of the message is invalid or not found."

Since Windows Server 2012 already contains "Windows Identity Foundation" as a Feature that's the reason it failed to installed.

So pause where you are are, first add "Windows Identity Foundation" as a Feature via Server Manager, once installed then continue and you can easily move on to the next screens...
