now there is 3 driftnet ways to temporally fix this
1=go to the main dayz folder in the steam folder and run it from there
2= if you tryed fix#1 and did not work or if you validate game casha and tried fix#1 and its not ruining the game at all try to go to exp and change back to staple
3=if fix#1-2 did not work try validate the game and exit steam open steam and run the game , first time try running it from steam if it did not work run it from the folder

this might reset you options to default or just make the game windowed like it did to me

one more thing if you run it from steam and it give you that it cant find the patch for the folder and then you clicked the X on the pop-up error then the CMD console show up dont close the CMD console wait tell it close it self
hope this fixed it now this is a temporarily fix not sure if they will fix it in a hotfix update or what but lets just hope so

PS.plz tell me if it works for you :) hope it works

Perhaps it has to do with the new battle eye update, Do you have antivirus software?

If you do I suggest that you do a full scan of your computer then temporarily disable the antivirus and give dayz another try.

New update when i run the dayz.exe in the steam folder it says im missing MSVCP120.dll, but when i run Dayz_BE.exe i get that long ass message. i tried reinstalling microsoft visual c++ 2013 like many said and that hasnt worked. Funny enough i tried it without antivirus no luck and i tried all that stuff Major with no luck at all.

I replaced the .dll file and now when i boot dayz directly i get this application error. "The application was unable to start correctly (0xc000007b). Click OK to close the application." I will continue to try and fix my issue and keep my note updated as i go along.

Try going into the steam folder
Steam\SteamApps\common\DayZ\_CommonRedist\DirectX\Jun2010\DXSETUP.exe

Hopefully when you run DXSETUP.exe it fixes it

You said you already installed the visual c++ but perhaps because dayz is based upon arma 2 installing the newest one is skipping older required files.

There is a folder called vcredist within Steam\SteamApps\common\DayZ\_CommonRedist
Perhaps if you reinstall the right one of these for your version of windows it will fix your problem?

Hi swiftkiller10 and sorry to hear about your trouble.
Please let me know if there are any .mdmp or .bidmp files in your C:\Users\<Name>\AppData\Local\DayZ\ folder and if so, please attach them to the ticket.
Regards,
Andy

swiftkiller10 dude no need for all that stuff just right click on dayz in steam click validate game casha and then after its done exit steam and launch steam again dont click dayz instead go to your folders and look for the steam folder and go to....steam/steamapps/common/dayz and then click on dayz not dayz_BE i think what should fix it all right for you :/ just dont do any thing the internet tells you

well I have great news after 3 days i log into steam today and Dayz had another update and installed something on my computer and is now working. i will play a bit now and hope it continues to work.

the only issue i seem to have now is the random global ban i got on my main account but i dont believe you guys can help me with that.

Good to hear it's working! I suspected the problem might have been something with incorrectly downloaded data, so a new update fixing it makes sense.
Sadly, we cannot help with BattlEye issues, please contact BE directly at support@battleye.com.
Thanks you,
Andy
