Sorry my bad I messed up. You have to open the game then while it is open go to task manager and then the process tab in task manager then right click on microsoft flight simulator x then properties. Then go to compatibility and change the windows operating system. Should say run the program under compatibility mode for windows 8 and make sure the box is checked. Then hit apply and the okay and the restart microsoft flight simulator x.
I did all of that - still crashed. But thanks for your help.
