About 96%-98% of Steam trainers work on Epic versions of the game and vice versa. It we offer no guarantee it will do so flawlessly. Just click the Fix button and manually like Steam’s .exe to it.
Trainers are made if the game is popular enough on that platform with WeModders. We don’t make trainers work with multiple stores on purpose, because one slightly different update between them will render the trainer useless for one or the other.
