Upgrading to Windows 10 and installed Steam client and then FSX SE install went okay but when I attempt to run the program I get the following message which by the way I get after installing SP2 on the Deluxe box version as well. Flight Simulator was unable to load some program files and will now exit. Please reinstall Flight Simulator to restore or repair program installation. I've tried uninstalling and reinstalling to a separate drive and no joy. I've found that others have had this problem but can find no solution for the either versions of FSX. Any thoughts and possible solutions would be appreciated with free GAS product to whoever can offer a solution. Thanks
