Yeah, it's not only for this anticheat, it's for Valorant's anti cheat aswell, the system is not running in test mode, already checked and tried to run it into test mode, so probably a system reinstall is advisible i guess, since it removes all the bloatware and you get fresh system with registries. I already tried a lot of things - scanning system, repairing with sfc scan, startup repair, autoruns to delete anything that might cause the problem, deleting aion's, activeanticheat's registries through regedit, does not work.

Literally checked, whether the command worked or no, the answer is yes it worked, but i'm still getting error.

I already wrote, that i tried that, It didn't work for me.

Okay, it's perhaps known error, with fix, but not for me atleast, i tried all that stuff which is mentioned in screenshoot and even reinstalled game 3 times, through client, through torrent aswell, tried 32 bit 64 bit, it shows as in it's anti cheat's fault. Would be nice if there is another fix or something. That brought me idea of deleting old registries associated with anticheat and client itself, if any mods/players know where they are located, would appreciate your information :).
