EDIT: My apologies!! We overlooked creating a new administrator user account on his OS. It... worked... so weird. Any way to isolate what causes that conflict ? What a hassle! Oh well, at least we can play now :D Hi everyone, I convinced my friend to join me in DayZ but he unfortunately had the same issue as the OP in this thread. Even worse, none of these fixes have worked for him. He has had a similar issue with punkbuster for BF4 and oddly, Skyrim won't startup on his computer either. Is there anything else that could help? I feel so bad for him, I'm trying desperately to get anything that could help. Much thanks,
