RFD G2 and XP PRO
I'm not sure if I understand your problem correctly, but if you want to install G2 upgrade over a previous RFD or Rf classic installation, make sure you didn't upgrade RFD or Classic to the latest version, because G2 will not install properly ( it will seem to install, but RFD or Classic will start...) If you did install the latest version... Then uninstall, delete the realflight directory, and start over again.
