A few days ago I ran into the problem, that certain applications stopped working (like overnight). By stopped working I mean that the system doesn't attempt to even start them anymore. I get following message (a Windows 10 style alert):
This app can't run on your PC
To find a version for your PC, check with the software publisher
This includes applications such as Thunderbird, Audacity, Steam and other 32-bit apps.
However 64-bit apps such as Chrome, Firefox, Edge, Ableton Live and all UWP apps seem to still work fine.
I also want to note that apps such as Spotify or Amazon Music, which I installed through the Microsoft Store, stopped working as well but without giving me the above alert (AFAIK they are Win32-based apps).
At the point in time I first discovered the error I ran Windows 10 1903. I did not investigate the problem and foolishly assumed the problem will just go away after an update to version 1909. Of course that was not the case.
things I tried: new admin account, turn off smart screen filter. but neither worked.
Here are my system specs: Ryzen 2600X, 16GB, ASRock B450M, Radeon RX5700 Microsoft Windows 10 Pro 1909 64-bit
Any suggestions what the exact problem is and how to solve it?
.exe
of one such app, Properties, Compatibility tab, and set "Run this program in compatibility mode for" to Windows 8.chkdsk
, (2) sfc /scannow.
