I have 6.5 running on an older laptop and just bought a new FAST laptop so want to move RealFlight to the new computer. Both are running Win 10 and the sim runs fine on the old one. I started with G4 from a DVD and that was updated in multiple steps to 6.5 by free upgrades and updates. It has the Elite controller. I really do not want to buy a new version as the old one does all I need. I have contacted RealFlight twice. I got no response the first time so tried again today. I hope that someone here can help.
