This app can't run on your PC

Hi Juliet,

I am having the same problem and Stephano.

How do I identify which application is causing the error message?

The problem is, I don't know what app is causing it. I will close all apps, and walk away from the computer and a minute later it pops up again. I go to Task Manager and don't see any apps running. I run virus scans and it says clean.

Thank you SOOOOOO much for this !!!!!! I've spent so many hours trying to find a fix it is mind boggling!

That message popped up every time I signed on to a new Windows 11 session (but not when I just unlocked the screen on an existing one). It just started up when signed one day after I did a Restart, even though I had NOT manually installed any new software. I also saw it on occasion upon closing a browser (Chrome or Edge). I made sure Windows 11 (including Edge and MS 365) and my Dell PC's software/firmware, plus my VPN and backup apps were all up to date - no help. (Obviously it was something that was on auto-update.) I emptied, checked and restored all apps that were in the startup directories, so I knew it wasn't the usual problem people talk about. I removed Chrome from my PC - no help. I did consider blowing and re-installing off McAfee, but I've used McAfee to protect my PCs for decades and didn't think there was any way it was anything of theirs. However, I removed WebAdvisor by McAfee when I got your Reply and (BANG!!!) no more stupid "This app can't run..." errors. Then I re-installed WebAdvisor over the web and (so far) I have not seen anything that causes it. Apparently, McAfee doesn't update that one when it updates the rest.

Have you notified McAfee about this?

I deleted a steam app and seems to have stopped. I think one of the steam games was causing my issues.

I'm running Widows 10 and am having the same issues. When I try to change Compatibility, Windows 10 isn't even an option. Windows 8 is the newest option available. Bios battery is brand new. Any clues as to what's going on yet?
