Thanks Brad.....I tried that, still no luck. Then, later, I woke up & recalled that trouble had started with recent Malwarebytes update, so I copied the 'download SupportAssist link' into the Malwarebytes URL Allow List and that worked first shot. So I'm happy! Thanks for your help & to the boys at Dell! Mike.
Supportassist just stopped working in my 3080, so deleted it & tried (many, many times to re-install. It downloads fine, but on the re-install comes up with the 'we were unable to validate a file for installation' message. My internet connection is solid & I have been unable to find a cure for this. Has anybody else had his problem.....and has anybody found a cure> Thanks for any advice! Mike.
