is back again: "Update failed. AV engine is not initialized" 3.13.121240.574

CIS on WinXP-32 SP2:
AV definitions updates stopped working after automatic update to ver 3.13.121240.574 :
“Update failed. AV engine is not initialized”

‘diagnostics’ found no problem.

reinstall didn’t help.

AV engine not initialized suggests that cmdagent.exe is not running and/or crashed.

Do you have any other security software installed that could conflict with CIS install?
No matter if Real-Time or OnDemand…

Can you check TaskManager to see if cmdagent.exe is running?
