I am seeing the same problem on my Windows 10 pro box as our German friend has on Windows 7 when i try to activate using F1 i get CTD i have not tried every trainer i have because i don't really use them a lot but i have some older games where i use the trainers because it makes the game more fun.
ill try to see if any of my newer games have that problem also and get back to you
tried the BF1 trainer no CTD BUT my PC almost went dead that trainer has serious memory issues and whats up with the name this is copied from task manager
~CheathappensTrainer9486.tmp i am no programmer but i am pretty sure that the program name should not be called that

All our current trainers marked as Trainer Manager Compatible store temporary files in the Work folder in this location here -> C:\Users\YourWindowsUserName\Cheathappens\
The tmp file you mention is one of them. All content of the Work folder is deleted when you close the trainer and is created newly when the trainer is launched. This tmp file always has its digits changed in the file name.
Exclude this Work folder in your security software.
