doucey592, I would strongly suggest that you don't use any other method to install anything into your flightsims other than manually doing it. Reason? If the programmer of the self install didn't do it right, or the programs installation directory is different than from you have the game installed, you can run into serious problems. There are other reasons, but messing up your game is a real good one not to use them.
Manually installing anything such as scenery, acft., effects and so on is really not that hard once you learn a few basics. You are much safer this way and you learn how the game operates. Take the time to read the tutorials here at Simviation. Grumpy's Lair here at Simv has some excellent tutes to get you started:
