In my case Instant Troops, Heal Selected Unit, Super Selected Unit do not work... I used the latest trainer (I have the latest patch of CoH2 installed).
I followed instructions from TXT file... other trainer options seem to work correctly.
Working all on my side.
Please make sure to download and use the US keyboard layout for Windows when using this trainer and press the related keys on your keyboard accordingly.
every time i click the trainer i get the message :
"unable to load cheathappenstrainer3205.tmp
unknown error" .
You need to create a scan exclusion in your security software for the Work folder which is located here -> C:\Users\YourWindowsUserName\Cheathappens\
