After a fresh install of Windows 8.1 Pro with Classic Shell installed, I installed Avast 19.2.2364 (build 19.2.4186.431) using the on-line installer a3b. By chance, one of the first things I did right after the install was to click on "This PC" and select "Manage". When I did that a pop-up window appeared with the title "CompMgmtLauncher.exe - Entry Point Not Found" and the text inside the window read "The procedure entry point _crt_atexit could not be located in the dynamic link library C:\Program Files\AVAST Software\Avast\AavmRpch.dll."
Using the "Repair" option from the Control Panel did not correct the problem. I also tired uninstalling, running CCleaner to cleanup the registry, and then reinstalling without success.
Is there anything else I should try?
