I get this error when i try to run FlightGear. It's my first time trying FlightGear.

Fgrun.exe is only a helper application which is not really needed to run flightgear.If fgrun.exe does not work you can still try to launch flightgear manually.Open a command prompt window and go to thedirectory where Flightgear is installed.Example:C:> cd C:programsflightgearbinwin32 (The location of flightgear can differ on your system)Then start Flightgear with the following option:C:programsflightgearbinwin32> fgfs.exe --fg-root=C:programsflightgeardata --aircraft=c172p --airport=KSFOThe option --fg-root=... must point to the data directory of flightgear, this can differ on your system. The option --aircraft=... selects the aircraft.You can list all available aircrafts by running fgfs.exe with the option --show-aircraft.And the option --airport=... selects the airport by using the ICAO code.
