Activation code
I have recently bought the Arma2 complete collection and installed all the parts for it. When I launch the game a window pops up saying when prompted I will need to enter the following product activation codes. My question is where do I activate them? They don't work directly through steam so is there somewhere I need to go on the game to activate them? The game seems to work okay but one of the codes is for the Army of the Czech Rep DLC which I don't seem to have access to... Any ideas?

Just click right button on game that you want to launch and press "See a product code" or the same

I have a similar question. If I go to the "Expansions" option on the main menu, I see that the expansion there are lite editions with option to buy them. I don't understand where I enter the CD Keys steam show me everytime I launch the game.

Run steam.exe as an admin then play both Arma 2 and Arma 2 OA as an admin to complete installation. If you have the expansions they will be fully installed when doing this too.
