ps,,also click on areofly icon and see if you need to check compatibility,, you may have to change your settings back to win xp sp 2 or 3 ,,,,also if you have installed a clean install of win 7 over xp you will find a file with old xp programs ,,you will find your old aerofly setup there,,,you can drag up flyrun to your desktop and run the old setup,,,but its better to delete that folder,,,because it will prevent a fresh areofly reload from working ..
