Thx for the info Mike.

Unfortunately the troubleshooter didn't find anything. I was able to uninstall and re-install the Photo App via the link you provided, but after that I still have the same...

Yes it is in the store, but is says "Installed" and only the option to open the app, not to re-install.
When I open the app that way, it just force closes in a sec without any message.

Hello,

From one day to the other my Windows Photos App stopped working... When opening a picture I get an error message like this:

55282

I don't know how to re-install the app either.
