This is the error I get when I start from the start menu. In the store under "Installed" when I click on Launch nothing happens.
Timeline before this: I downloaded the game to C: it worked fine. Moved the app to D: - it worked fine. Both C & D are on the same internal M.2. Made a restore point for C. Next day FlightSim found 10 GB of updates it wanted to download. I wanted to wait with that because of my crappy connection where I am now. I also changed where it wanted to download to from C to D and exited the game. I then restored C: to the restore point I had made the day before when everything worked fine. This because I had played around with some unrelated things I wanted to get rid of.
What do I do? Was thinking of reinstalling Windows and start from scratch, but downloading 100GB takes forever, and when I know I got it already on D:\WindowsApps which I am denied access to! Any help would be appreciated.
