Yeap, unless there was a recent patch/update, it's been working with GOTY.
You wrote, [...once you click F-11...] Did you mean F-1 as in when you activate the trainer?
If it's the Steam version, did you use their verify File Cache tool?
If it's GOG, I believe their Galaxy app checks the files as well.
You gave the trainer Admin Rights?
I clicked F1 yes typo. Already verified integrity and gave admin rights to both the trainer and the witcher3.exe file.
What file in the temp folder i have like 100 files?
