Have you tried installing it in FSX? A lot of aircraft work quite well although the textures are usually a little slower to load. Some aircraft have minor problems which you can live with but some unfortunately don't work, especially if they use old gauges.

It is possible to convert the old .gau gauges files to xml, using the same bitmaps, so they can be used in FSX.
I have done it a few times when nothing else was available for special gauges.
It´s a lot of fiddling with the bitmaps and also writing new xml-files, but can be done.
