help?

seriously, HELP ME

I have the exact same problem. I've searched all over and no one seems to have an actual solution. Someone please help. I'd like to stop manually updating DayZ :P

Blairsingh found a fix in the other thread. Go to C:\Windows\Microsoft.NET and then rename the "assembly" folder to "assembly 2". Then try the 4.0 standalone installer again and it should work. Good luck!
