Try to on and off your internet and run the update, hope it will works.
Add your client and game folder as exception/exclusion at your AntiVirus (or turn off your AntiVirus)
Launch the AutoUpdate.exe as Administrator
That error comes from lacking runtime library .
Make sure you install Microsoft visual C++ redistribuable. Preferably the latest.
Visit Microsoft official webpage to get it.
I've experienced this before when my OS (Win xp) then I decided to upgrade it, I think your antivirus is the problem, try to add the autoupdate.exe into your exception list and run it as administrator. I hope it will works . Good luck!
Dude, install microsoft visual C++ redistribuable...what's so hard to understand? stop following white horses with blocking the game in all antiviruses.
can u show me a picture from control panel of the microsoft visual C++ u have installed in there? (add/remove programs, scroll till you see Microsoft visual C)
u need the previous versions of it as well. ofc for the correct windows version.
