Can anyone explain to me how to install DayZ when I have all the Arma stuff on steam? I tried six launcher but said it couldnt find the key or something like that.
http://www.arma2.com/beta-patch.phpDownload that. Should work out. If it doesn't install manually by torrenting the .pbo files and putting them into arma 2 operation arrowhead/@dayz/addons. From there, go to the arma 2 ao launch properties and set it as -mod=@day.
However, other installed addons always conflict with dayz because the addon's signature is never accepted by the server. If you installed any addons by pasting them into the extensions folder, you might just be screwed.
