When i run the game it says Uplay not found, Untrusted system file (C:\Windows\System32\uxtheme.dll)
Verifying the files did not help as well as reinstalling the game.
Reinstalling uplay and the anticheat itself also didn't help, but here's one thing: the issues doesn't appear anymore if i delete certificates folder in the EAC but in that case uplay just doesn't want to run the game due to some files in directory missing, although it fixes the issue, the launcher does not let me start it without that folder with certificates.
Hey XTaurusXSilverX - welcome to the Ubisoft Forums! I'm sorry to hear of your issues with running For Honor on PC due to this EAC error.
Did you already find our support article regarding EAC error messages, and perform the troubleshooting listed? If not, can you please do so, and let us know if the game launches as normal after?
