I have the same error associated with a .Net Framework error.


I resolved the issue with a complete rebuild of performance counter:

lodctr /R and winmgmt /resyncperf.




Same issue when install WEM Agent 1912

And .NET Runtime error before
Application: Citrix.Wem.Agent.Service.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Solution worked too. Run lodctr /R from c:\Windows\SysWOW64 if have err "Unable to rebuild performance counter setting from system backup store, error code is 2"

(Windows 2016 , WEM Agent 1912)
Thank you so much!
