OSname equals Microsoft Windows Server 2012 R2 Standard but AdfsVersion equals 2.0. How can this be? What to do?

Question

Excerpted results from PowerShell query:

PS C:\Windows\system32> Get-AdfsSystemInformation
OSVersion                 : 6.2.9200.0
OSName                    : Microsoft Windows Server 2012 R2 Standard
MachineType               : VMware Virtual Platform
AdfsVersion               : 2.0

PS C:\Windows\system32> Get-AdfsVersionEx
2.0

I have read several places (the actual quote) (a second reference) (a third reference) at AD FS 3.0 conforms to this statement: "the file "C:\Windows\ADFS\FSConfig.exe" DOES NOT exist (but the folder "C:\Windows\ADFS" does)". This is true for my server.

It does say Installed.

PS C:\Windows\system32> Get-WindowsFeature ADFS-Federation | FL InstallState
InstallState : Installed

The operating system version 6.2.9200 is Window Server 2012 R1, not R2. You need to provide the output of the PowerShell command: Get-WindowsFeature ADFS-Federation. If it doesn't say installed, I would speculate that server was an inplace upgrade from 2008 R2. The built-in ADFS version for Windows Server 2012 R1 is 2.1. The built-in ADFS version for Windows Server 2012 R2 is 3.0.

OSname equals Microsoft Windows Server 2012 R2 Standard but AdfsVersion equals 2.0. How can this be? What to do?
