StarPrincess, unfortunately I don't have Windows 11 and can't test this. I'll check around to see if anyone else has problems running the game on Windows 11, but I had a couple questions for you to help me troubleshoot:
- Did you try the 32-bit or 64-bit version of the game? (It's possible the 64-bit version is more likely to work.)
- Can you try right-clicking on LostArt.exe and in the pop-up menu that appears, is there a way to run it in compatibility mode for Windows 10?
