|Dataease has versions for DOS and for Windows. Which version are you trying to run? If it's the DOS version (very old) it will probably not run on a 64-bit system. If that's the case, I would recommend either using a VM or installing DOS-Box.|
If you have the Windows version, it should be compatible with Windows 7. I don't think they released a version specifically for Windows XP.
Also, typing in ALL CAPS is considered shouting and rude, so in future, you may want to re-think that. :)
