It might be Windows 7 then, yes.
About Impervious to Attacks, it makes sense when you die, activate this option and then you can stand in front of 3 guys who try to beat you up but always fail.
Okay, I'll wait patiently until someone make it work for Windows 7, or can tell me what's the thing(s) I've missed
Impervious to attack was working on the previous trainer version, yes I remember now that your character had to die once before applying the cheat, but then the note are inaccurate:
"Numpad 2: Impervious to Attacks - You may have to have taken damage
at least once. Toggle this on and most things cannot harm
you!"
"You will have to die once before" would help many players who get stuck not knowing why.
Edit: tested with DLC Nightfall to no avail 😭
After I dusted my Windows 7 PC I can confirm your findings. Please PM Caliber directly about it, maybe he can help you out with this.
I am not sure how to help here. I do not have windows 7 any longer, it's literally not even supported by Microsoft any longer.
Microsoft ended mainstream support for Windows 7 on January 13, 2015, but extended support won't end until January 14, 2020.
I also do not own the DLC.
Likely the way Unity works on old Windows 7 must be compiling the scripts differently or something, or the trainer is no longer able to attach to old Windows 7 games (api changes?)
I am not even sure why there would be an update to Windows 7 that would change the way the trainers work with it?
I did recheck the game this morning and the code is working 100% on my Windows 10 install.
best,
Cal
