I have had FSX:SE for awhile now after wanting to try a different platform from X-Plane..  I bought and installed FSX:SE, and messed around in it for a few days.  I ended buying the Embraer E-jets addon and messed around in that.  Then one day I wanted to play FSX when I got this error: "Failed to start game (unknown error)."  I have uninstalled and reinstalled the sim numerous times without any luck.

 

If you know how to fix this issue, please let me know!

 

Thanks,

Ben

Hi Ben:

 

There's not a lot to go on here, but one thing that comes to mind is permissions.

Where did you install the sim? If it was in "program files" this could be the problem. It is known to cause permission issues.

Try installing it in another location.

Before installing it, do a check of your registry and ensure there are no entries of your previous installations left behind.

If this fails, I would submit a ticket to Steam.
