HELP WITH COMMANDER!

[ixRazorxi (DayZ) 0]

I just recently bought Arma II: CO and when i download DayZ Commander, it doesn't load the game. I get this message when i try to launch the game saying this. "There was an error launching Arma2 with DayZ. Please check your settings, verify your game directories, and try again. Details: The system cannot find the file specified."

I don't know what to do. I have both of them downloaded onto my computer and on a lot of peoples under game directories on settings i see the second OA directory says operation arrowhead, mine says the same thing twice "C:\Program Files (x86)\Bohemia Interactive\ArmA 2" I've tried overiding it and putting it to what other peoples have said but it didn't work. Please help. Any questions that you have that might be needed to help me please ask. I have also done as some people say and open both games and play them i did that. I deleted and uninstalled the commander played the games on bootcamp and messed around a second, then reinstalled the commander. Still the same problem.. HELP?!

if you have a fresh install of Arma 2 and Arma 2 operation arrowhead, try to run those games once to generate registry keys on your computer. Launch Arma 2 first, then Arma 2 OA Combined Operations. Try DayZ Commander again.
