Unable to sign in to Visual Studio 2013 on Windows Server 2012 R2

I just recently completed an installation of Visual Studio 2013 on Windows Server 2012 R2

As many developers already know, Visual Studio 2013 now requires activation.

There are 2 ways of activating Visual Studio 2013:

2. Enter the Visual Studio 2013 Product Key manually.

NOTE: With the recent release of Visual Studio 2013 Update 2 and Windows Server 2012 R2 with Update seems to have at least resolved the Visual Studio 2013 Login issue.
