New motherboard, MSFS won't start

Had to replace the mobo, but same CPU, SDD and everything, so all looked just like the last time I shut down when I started up. But windows needed reactivating, which went fine. But MSFS won’t start, nothing happens when I click the icon on the desktop or ‘launch’ in the store. I am logged in the store and xbox. Any help please?

go to Apps, find Microsoft Flight Simulator, click, Advanced Options, click, scroll down and choose the gray Repair button.

I’m afraid that didn’t help, same result. There is also a Reset button, but that deletes the app’s data, and I’d rather not that. Any other suggestions?

Are you able to launch MSFS if you directly click on the .exe from the installation folder?

I was looking for that but couldn’t find it, is that folder close to where the community folder is?

Make a back up your MSFS. Simply copy the folders in C:\Users<username>\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages

I found there was a problem when I tried this a few days back. Windows is stating I cannot copy files from there. I got past this by making a rar (compressed) file on another drive.

Once you have a copy of your files, uninstall MSFS totally.
Reinstall it to reset the errors you have currently.

When MSFS started to do the big update close it down. Restore your files back into place.
This should sort out your issue.

Suddently it’s starting OK! Not sure, but I think what happend is when I reactivated windows, the PC was given a new name, DESKTOP_something, (new username?) I changed that back to what it was before. I also clicked ‘Repair’ in the app window, so not really sure what did it, but now it seems to run as i should. Thanks for your help!
