Hey guys, I had this problem eariler this week, but me and my group found the solution. First open up Six Launcher, Click Verify Now Download the 1.7.2.5 Patch manually from the Dayz website, I used the torrent link. Once downloaded Un RAR files if needed Open C: Go to where your Arma II dayz mod is located in the sys files. mines -C:Program x-86 -Steam- -Steamapps- -Common -Arma II Operation Arrowhead @dayz mod -open folder "addons" -Copy and Paste new 1.7.2.5 (the ones you just downloaded) files into "addons" folder (Files will look the same) -Launch Game -when the main window opens where you can see the single/multi/etc look at the version number (Should be 1.7.2.5) -Join a 1.7.2.5. server, -Destroy ZEDS! Note: you have to manually patch it everytime you close the Six Launcher. When you verify, the Six Launcher rolls it back to 1.7.2.4./ So in turn you have to manually update it to 1.7.2.5.
