Try Verifying cache on BOTH Arma 2 and OA (through Steam), by Right-click > Properties > Local > Verify blah blah blah. Takes about 5 minutes for each.

When that's done run EACH GAME through to the in-game menu. Then close steam and all that and Run as Admin.

ALWAYS run EVERYTHING as admin when dealing with DayZ.

Mine keeps saying 1 file fail and will be required how do i fix that?

Also, just run ArmA II OA and Combined Ops really quick (Boot Camp or whatever) if you are using the Steam version and then run DayZ again.

I had this exact problem when i reformated my pc and this worked for me.

I have this problem only when I try to run OA or normal ArmA 2, when I run CO it's fine.

Thanks for all of the replys.... but the problem was there wasn't a serial key in my operation arrow head file, so im reinstalling steam since i've tryed all of the stuff and redoing all of it. also i couldn't even get oa to run.

I had this problem last night, Do as this guy says, close out all things related to Arma, Exit out of steam, Run Steam as Admin, Verify both, wait a few minutes, run Arma II first, then OA, Then CO, that fixed the problem for me, though I have been seeing others that said doing this didn't work for them..

The problem im still having is that it isn't installing my Cd key. does that mean i have to buy a hole new game?

im trying to verify it but i don't know how, i went to properties and hit run as administrator, what do i do after that? do i have to go to local, because i cant find it. oh yeah i get a message that says failure to contact key server.

Run Arma 2 and the addon version once, exit, and try again, this is also in the instructions for Steam users.

This. This is your problem, and your solution. DayZ won't work until you run Combined Ops first (assuming your a Steam user). Just open up your game library in Steam, right click on Operation Arrowhead, and select 'Combined Ops.' You can exit out after you get to the main menu.
