I obtained FarCry 3 through the Ubi35 celebrations, can confirm the game is still using the 1.05 build however when trying to activate "the cheats" the trainer crashed and I couldn't reload the trainer. I am using Windows 11 on my gaming PC.
Also, is there any way to convert the format of the trainer into your newer format? I.E. Like with Outriders, Cyberpunk 2077, etc.
---EDIT---
I just went into my uninstall program and noticed a program called PunkBuster has been installed with an FC3 reference, do you think this could be causing the issues with your trainer?
It wouldn't surprise me that Ubisoft added an anti-cheat program especially after making it a free game during the Ubi35 celebrations.

The 1.06 version apparently shows in game as 1.05 still, which is confusing. There is a mod to downgrade from 1.06 to 1.05 available. i believe 1.06 as released around the same time as Far Cry 3 Classic.
These are all problems I have been having too. I have requested they update the trainer via the update notification system as they asked, so if yourself and any others with the problem could do so as well, we can hopefully get the trainer issues resolved.
