Hi Colin, thanks for your question. The old Program Compatibility Wizard from XP is not in Windows 11 anymore. The same tools are built in. Right click the game shortcut, choose Properties, go to the Compatibility tab, and set it to run in Windows 7 or 8 mode.
You can also right click the shortcut and select Troubleshoot Compatibility to let Windows test settings for you.
Best regards,
Arlene D.
