Well i got Dayz yesterday and when i tried to run it got this error
Addon ‘dayz_anim’ requires addon ‘CA_Dubbing_Counterattack’
To fix this problem you have to copy AddOns folder from Arma 2 game folder:
C:\Program Files (x86)\Steam\steamapps\common\Arma 2
To here
C:\Program Files (x86)\Steam\steamapps\common\Arma 2 Operation Arrowhead
Good luck
