Check the event viewer of windows for a crash entry about the trainer. If there isn't one its mostly likely your AV still blocks the trainer from running.
Is it possible its the authentication that is failing? I've tried it with Bitdefender turned off, with the trainer exempted from scans / threat detection, etc. This is a Win10 machine with Edge and Chrome.
This trainer doen't seem to work with the GOG version of the game, all I get is crashes. is there something I'm doing wrong or is it just the wrong type of trainer, if you need the .exe of the GOG version I can send it. But as always, keep up the awesome work you do.
The trainer is solely written for the Steam version of the game.
If you like to have a trainer for the GOG version you can gift us the game and sent it to chris@cheathappens.com
