Hi Awzumcoltz22,

Just to confirm; did you set the
"C:\Program Files (x86)\Steam\steamapps\common\DayZ\DayZ.exe"
"C:\Program Files (x86)\Steam\steamapps\common\DayZ\DayZ_BE.exe" and
"C:\Program Files (x86)\Steam\steam.exe"
to run as administrator?

Also (I know you mentioned it, but still), could you try the following steps please:

  1. Download and install Microsoft Visual C++ 2010 Redistributable Package: [^]
  2. Restart your pc.
  3. Download and install Visual C++ Redistributable Packages for Visual Studio 2013: [^]
  4. Restart your pc.
  5. Launch DayZ (run both Steam and DayZ as administrator if needed).


Same here I've had the same problem for almost a week and I've done all the steps shown by Jstewart to no avail.

Yes i have completed all of these steps but the game will still not launch.

I had exactly the same problem. I deleted the launch-parameters of DayZ and the DayZ-Config directory. After that, everything was fine.

How do you do that?

Yes, how do you do that?

Sorry paper26, i tried that but it didn't work. i had no launch-parameters and i think i deleted the config file (the one in the Dayz file in the documents) and i don't have an error code now if i try to run from the desktop shortcut, it just says dayz has stopped working.

Hi Awsumcoltz22 and sorry to hear about your trouble.
Please try reinstalling your graphics drivers as well.
If that does not help, please go to your AppData folder (C:\Users\<Name>\AppData\Local\DayZ\), delete the contents, reproduce the crash (by launching the game) and then attach the newly created AppData contents to this ticket in a .rar.

Problem fixed i had to update my drivers and then go to my nvidea geforce experience and i scanned my games and had to set Dayz to run on optimized settings! but thank you very much for your help and the new update is awesome My friend and i found one of the trucks right when we got on but to anyone who is having this problem be sure to check your drivers and make sure to set to optimized settings
