Identify SCOM Agent Version from the file system on SCOM 2012 R2 and SCOM 2016 Agents

When writing my SCOM Agent Update MP  I needed a way to get the SCOM Agent version from the file system.  There is one file that gets updated in every Update Rollup.  OMAgentTraceTMFVer.Dll that is located where in the \Tools\TMF directory where you installed the scom agent.  In my case C:\Program Files\Microsoft Monitoring Agent\Agent\Tools\TMF\OMAgentTraceTMFVer.Dll

I wrote this script to read the file version of this file to identify agent installed version.

Here is a similar VBscript that will pull that data. It works with SCOM 2012 R2 and SCOM 2016

Set objShell = WScript.CreateObject("WScript.Shell")
sngVersion = objShell.RegRead("HKLM\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Setup\InstallDirectory")

Set objFSO = CreateObject("Scripting.FileSystemObject")
fileVer = objFSO.GetFileVersion(sngVersion & "Tools\TMF\" & "OMAgentTraceTMFVer.Dll")


select case fileVer
   case "7.1.10184.0"
      urVersion = "RTM"
      agentVersion = "2012 R2"
   case "7.1.10195.0"
      urVersion = "UR2"
      agentVersion = "2012 R2"
   case "7.1.10204.0"
      urVersion = "UR3"
      agentVersion = "2012 R2"
   case "7.1.10211.0"
      urVersion = "UR4"
      agentVersion = "2012 R2"
   case "7.1.10213.0"
      urVersion = "UR5"
      agentVersion = "2012 R2"
   case "7.1.10218.0"
      urVersion = "UR6"
      agentVersion = "2012 R2"
   case "7.1.10229.0"
      urVersion = "UR7"
      agentVersion = "2012 R2"
   case "7.1.10241.0"
      urVersion = "UR8"
      agentVersion = "2012 R2"
   case "7.1.10268.0"
      urVersion = "UR9"
      agentVersion = "2012 R2"
   case "7.1.10285.0"
      urVersion = "UR11"
      agentVersion = "2012 R2"
   case "8.0.10918.0"
      urVersion = "RTM"
      agentVersion = "2016"
   case "8.0.10931.0"
      urVersion = "UR1"
      agentVersion = "2016"   
case Else
      urVersion = "Unknown"
end select 

wscript.echo "Agent Version: " & agentVersion
wscript.echo "UR: " & urVersion

Here is the script in Powershell.   Modified from Kevin’s Agent Management Pack.  https://blogs.technet.microsoft.com/kevinholman/2017/05/09/agent-management-pack-making-a-scom-admins-life-a-little-easier/
