Yes, you can play the game on Windows XP. I have downloaded the version through the download page at Software Informer and it works just fine. However, the game will give errors when you attempt to launch it in a modern version of Windows (eg. Windows 8/8.1). The game installed correctly, but I couldn't launch it properly since I encountered errors. On Windows XP it should be just fine.
