i get an error that says:

The application was unable to start correctly (0xc000009a)

i havent played the game in a month trying to fix it sooo please anyone help me

Same here

im tired of this i just installed everything back and disabled my anti virus and stll i cant play

Okay I was able to start the game by going into program files and opening dayz.exe. But after joining a server battle eye tried to update and now DayZ wont open at all. I think there is something wrong with the dayz_be.exe or dayz.exe. I say this because for a brief second while battle eye was updating it said to launch dayz through steam or dayz_be.exe with launch parameters like 0 1 or something. So I think battle eye is the blame for this.

Try this:

I HAVE FIXED IT!

I went into C:\Program Files (x86)\Common Files\ and deleted the BattlEye folder.

Next I disabled my Anti Virus and Firewall.
I couldn't turn off windows firewall so I added a rule for DayZ_BE.exe and allowed all connections.

This is VERY important, because without doing this i couldnt get battle eye to update<<<<

Now I can start DayZ and BattlEye installs and the game works!

i fixed it
it wasnt that it was that i use an xbox controller and i had an addon on dayz for better preformance with the control... in other words smoother like if i was playing with keyboard... i deleted it and now i am able to play...and no one helped me doit....
