The stub cannot run installer/updater executable (code 0x3)

Avast Free Antivirus / Premium Security

I’m some problems running and updating Avast. I can’t update anything from the program, receiving the message: “The stub cannot run installer/updater executable ‘C:\Program Files\AVAST software\Avast\setup\Sfx\instup.exe’ (code 0x3)”. I’ve tried uninstalling and reinstalling the program, but can’t because of the above error.

I’ve attempted to use avastclear.exe in safe mode and the same message was shown.

I’ve attempted a clean install, and everything went the same way.

I found a very similar problem in the forum (https://forum.avast.com/index.php?topic=168069.0) and the conclusion was that I might need a more tailored fix. I ran a FRST scan and have attached the results. Hopefully, I can find some help!
