XP is based on 2000. I have a game that whenever I load it, I get a popup that says it's "not designed to operate under Windows 2000". But the game still runs fine -- it just recognizes the basic nuts and bolts of the system.
..get a popup that says it's "not designed to operate under Windows 2000".Have you downloaded the lates compatibility updates from MS? If that doesn't work, check the properties of the game, click on 'Compatibility' tab and check the box (for designed OS). That might take care of it.
