Unable to update virus definitions - MSI.dll
« on: September 10, 2022, 03:44:46 AM »
Hi when I attempt to update the virus definitions manually on Windows 11 I get the following error:

The code execution cannot proceed because msi.dll was not found. Reinstalling the program may fix this problem.

Problem is that I can't even run the installer as it gives me the same error.

Any assistance with this is appreciated.

Am running Windows 11 with 64 gig Ram. I have two harddrives and Avast is installed on the main C drive.
