Gears of war 4 has just been updated just now, the trainers don’t work anymore 
I can’t beat the game on insane without my god-mode and infinite bullets. I’ve been sticking with Cheat Engine just so I’ll wait for WeMod to update Gears 4 trainer. Please update it, I really need the trainer Thanks!!
Might be best to write it in here: Gears of War 4 Cheats and Trainer
Makes it easier for the maker of the trainer to notice 
Closing this thread since the Gears 4 tool was updated yesterday, the OP was notified and confirmed it was working!
