From the trainer instructions:
This game creates code on the fly.
Before activating this trainer you must be INGAME
And you must have opened your inventory ONCE.
Then press F1.
Do you activate our trainer as described?
When and where does the crash happen for you? Activation? Launch?
What's your Windows version and what security software do you use?
It happens when attempting to activate the trainer itself, after I've loaded the save and opened the inventory once.
And my Windows is Home, Build 10.0.16299. I use Defender, and get the same result when deactivating it. The old trainer also works with Defender activated, if that makes any difference.
