Retrieving the COM class factory for component Access Denied Error


While trying to run Azure Pipeline for Loadrunner Professional Tests, got below error

Retrieving the COM class factory for component with CLSID {E933439A-81A1-11D4-8EEE-0050DA6171E8} failed due to the following error:80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).  
  1. Somehow figured out that this CLSID is associated with wlrun.LrEngine, but i couldn't find wrlrun.LrEngine in Dcom application list (dcomcnfg.exe) in my machine.
  2. I can see the wlrun.LrEngine in registry, but cannot see in the Dcom config folder. (Component Service >> My Computer >> DCOM config )
  3. What could be the possible reason behind this, or am i searching in wrong place?

Solved this issue by opening Dcom Config for 32-bit Applications:

  • Go to Start | Run
  • Type MMC -32 and click Ok
  • Go to File | Select Add/Remove Snap-in option
  • Add Component Services option in Management Console application
  • Then follow the path to Dcom Config

And Boom! i found wlrun.LrEngine under Dcom.

  • And further gave appropriate permissions to it (Right click >> properties >> security >> Click customize - edit and add permissions)
