Hmm, the tmp file created for me is always the same: ~CheathappensTrainer.tmp in the Windows tmp folder.
Please try a wildcard exclusion like this -> ~CheathappensTrainer*
As it is always recommended to have just one folder for our trainers (a necessity when using our Trainer Manager) and have this folder excluded from any antivirus/other security software scans he was asking about the created tmp file which a lot security products tend to flag more often than the trainer exe.
Some tmp files are created in the Windows tmp folder, some in the -Work- folder here -> C:\Users\YourWindowsUserName\Cheathappens\
As far as I know the trainer is working, you download it and extract it to any folder that you have added to you antivirus exclusion list.
Find your antivirus on this page for further instruction if needed
Do you use a Webroot as security software? if so -> Open Advanced Settings -> select Scan Settings -> uncheck Detect Potentially Unwanted Applications -> Save settings and create an exclusion for the trainer file
Nope, I've always used AVG and all my trainers are excluded and safe from it. This is the only trainer that's causing CTD but like I said "occasionally", since it only happens once every 3-4 hrs of gameplay
