Reboot PC when done.
Also double check that neither your AV (if you have one) Or windows defender blocks the trainer. they can still block it without sending a notification so double check that.
The .net core is what i meant by the runtime files. my apologies from lack of clarity. And I disabled my 3rd party AV, and then went in and killed windows defender as well. Then just for kicks, I whitelisted the trainer in both of them just to cover my bases.
I have to assume it is something with this specific version of this one trainer. I tried it on my other computer as well with the same results. I am using a previous version that works for at least a couple things, so I'll likely just live with that until a new one is released. It isn't the end of the world, and CH puts out so many great trainers that I'm not going to lose sleep over a rare miss.
