Look at the box for system requirements. Does it say it works with XP? If so, then something is interfering. Maybe your antivirus is trying to protect you. That’s just a guess, but games generally do funky non-standard things things inside your computer, like direct access to protected areas of memory, etc. You may have to tell your AV to let this program have unrestricted access. Now, I’ve never played this game. Is it a recent game? Or an older game? If it’s an older game, you may be SOL or have to spring for a used computer with Win 98 on it or something… One thing I can tell you is that XP doesn’t play well with games, even games designed for it. And especially if it’s an older game written for, say, Win 95 or Win 98. And don’t even try to play a old DOS game in the XP command line window…it just ain’t gonna work.
