Do you have the error message or check for the exact error in the Windows application log?

The Performance counter issue is a generic issue not just related to the Privilege Management Console adapter. it can be fixed using this from Microsoft to rebuild the Performance Counters https://learn.microsoft.com/en-us/troubleshoot/windows-server/performance/manually-rebuild-performance-counters

If you can’t rebuild the performance counters anything you attempt to install that uses performance counters will fail, including the Privilege Management Console Adapter.

Attempt this from an elevated command prompt and on own risk!

1. Check if the BeyondTrust Privilege Management Cloud Adapter is visible in Servics.msc. if visible remove it using this command. 

sc delete "IC3Adapter"

2. Rebuild Performance Counters, together with extensible and third-party counters, type the following commands at an Administrative command prompt. Press ENTER after each command.
3. cd c:\windows\system32
   lodctr /R
   cd c:\windows\sysWOW64
   lodctr /R
   WINMGMT.EXE /RESYNCPERF

3. Stop and restart the Performance Logs and Alerts service.
4. Stop and restart the Windows Management Instrumentation service.
5. reboot

I think that should be it to get it resolved. As stated above if that does not work I would just re-image the machine.
