This is now July 2020, and the trainer won't launch (with Admin credentials) in Windows 10 x64 version. I can run other trainers from CH, but not this one. Disabling AV and Firewall didn't help. I have also tried running the trainer in a Win10 Sandbox virtual machine with nothing installed, and it won't launch there either. There is no error message, and I can't see it in Task Manager. It just won't launch.
Maybe one of the Win10 updates made the trainer incompatible? This is Windows 10 Pro x64 build 18362.
I just downloaded and ran the trainer just fine on Windows 10. Something on your machine is blocking it.
