I just installed the Rage Complete Edition, this trainer works for me - all options. It is most definitely a false positive from any Anti-Virus as trainers use memory and look at the game .exe files which is why Anti-Virus software detects it. Either Disable the Anti-Virus Software while playing, or create an exception rule to ignore the Trainer.exe. Run the game and the trainer with Admin Privileges Rage.exe (works).
The trainer doesn't seem to work with Rage64.exe though. -- Thanks for the Trainer Mr. Antifun
