I "think" it may be because it runs in ms-dos not windows?
You may be out of luck.
I had some beaut graphics-intensive games that ran in DOS under Win 95 and, I think 98, but not 98SE (it's been sooo long ago
) but won't run under XP.
I think that MS has abandoned DOS backward compatibility in XP, except for basic stuff - most of my arcade games work ok, but none of the older fancy graphics stuff.
Shack may have a point, too.
