I have Real flight G4 and all the disks but when i got my new laptop, (running on windows 8.1, as that might be the problem), i tried to install RF4 using the conventional way, (putting disks in old computer with drive, cd files into thumb drive, etc...) but when i finally got all the files onto my laptop, i try to run it. it goes to the installer, and when i click "install" It tells me that i NEED the disk in the computor for it to work. Is there a way i can get around this? I have the controller and everything. I have the required space and everything so im feeling quite hopeless right now.
