Trouble Installing ArmA 2 OA

[faded 13]

I've tried to install OA now for the 2nd time and when it finishes installing a message comes up saying, "Do you want to reinstall ArmA II AO..." And I clicked no then it starts to extract then when it reaches 100% Extracted it says that the install is corrupt or something.

Are you installing from Steam? Also, have you installed Arma 2 before trying to install the Operation Arrowhead expansion?

Or screenshots would also be helpful.

Press print screen on each step of your problem, and Ctrl-v into paint.

Obviously not steam.
