I have REX, UTX, GEX, and FSgenesis media bundle which has all sorts of terrain mesh. I recently read somewhere that Windows 7 has a hard time installing sceneries and I was wondering if my sceneries were actually working in game or not. I was wondering if there was anyone who owns GEX, UTX, and FSgenesis terrain mesh could post in this thread telling if when they go in their scenery library in FSX, if there is any entries pertaining to these programs.
