I had this problem just now and came upon this post I install just the x64 and now no problem
Tahnk you myu friend, now I can use the trainer.
Obs:. it's possible to make the trainer manager check is the trainer would run or not, if not, download this version provided by 0x90 ?
did you install BOTH of these?
Huh. Weird. Been using your trainers for years, never had any issues with .net so far, but today the new Frostpunk trainer complained about it. Downloading the x64 version of that seems to have solved it, though. Haven't touched my .net installations in months, so it's weird that I'd have to install it again now when trainers worked like clockwork just a few days ago. Did anything change with the very latest trainers?
