Steam

Steam

Try this http://www.dayzcommander.com/

Go to the options, and select options: Use steam overlay AND replace beta exe.

Then go to the versions tab, and update everything.

Try to launch the game using the Commander now. If it wont work, go to the options again, remove the option "Use steam overlay" and try to run dayz using Commander again.

try this:

- exit steam

- run steam as administrator

- run ArmA2 to main menu and exit

- run ArmA2: Operation Arrowhead to main menu and exit

then try to run it as you normally would
