Upgrading to Windows 10 on a brand new PC and installed FSX Deluxe box version, then SP 1 FSX install went okay, the installed SP2 and that's when it went off the rails. 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
