What version of WMF am i running

Hi all. I have a 2012 R2 Datacenter VM in my lab.

I want to install WMF V5 so that I can do a MVA course on line however when I try to install WMF 5 I get a generic answer saying it is not for this machine. I realise the response could be due to the component already being stalled by what I like to do is run a command and have it tell me whet version is installed. Is this possible?

I have run  $PSVersionTable

Which returned:

Name                           Value
----                           -----
PSVersion                      4.0
WSManStackVersion              3.0
SerializationVersion           1.1.0.1
CLRVersion                     4.0.30319.34014
BuildVersion                   6.3.9600.17400
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0}
PSRemotingProtocolVersion      2.2

Is either of those WMF by chance?

Thank you for looking
