Try downloading FMS; it's free. RealFlight G2 is copyrighted and would be illegal to download w/o paying for it. Actually, even if you do pay for it I don't think the manufacturer offers a download service for the application.

Be careful how you word things on this board. Many people have hinted that they wanted to steal the software and received a lot of negative feed back. Of course, you're not trying to steal it right?

Hope this helps,
