Whenever I try to use this trainer it says 'Trainer can not find game'. I possess 'Napoleon Total War' with all DLCs. Is this causing the error?
I ain't using any mods. I start the trainer with administrator rights. Tried to alt+tab out of the game to inject, too.

Downloaded the game with all available DLCs, excluded the trainer exe from any AV scans, ran the trainer with admin rights, started the game, pressed 'F1' at the start menu and got 'Activated' for confirmation.

Again, I only tested the first 4 options of the trainer and it still works as intended.

All trainer options are tested and working just fine for Napoleon: Total War. The game runs pretty great and the trainer is working without a hitch. This is one of the TW that worked pretty dang well with a trainer, before you had to reset everything each turn.

So if you're reading this, feel free to give it a go. Steam version on Windows 10.
