Can I move my installation to a new computer?

[Stillglade]

I have a manual install of Arma II Free (with a key from Steam as the key generating URL was down) as well as a retail boxed copy of OA installed on my laptop (I am one of those new users who has been playing DayZ for the last couple weeks). Now I want to move my installation over to my Desktop. Is there anything special I have to do? Is it gong to think my CD Keys are already in use? During installation on the laptop at one point it asked about needing the disc in drive or another option to register the key online which I did. Will this option still be available on my Desktop and will it work? Can I keep it installed in both places as long as I only use 1 online at a time? I figured it would be better to ask before I tried to avoid any issues. Thanks in advance for your help!

NP if don't use the laptop and PC at the same time on the same server I think but wait for some mod to answers, too

You can have arma 2 installed on two computers but you can play Multiplayer only on one of them. You cant play MP on both computers in the same time.

Just following up that this did indeed work. I used the same CD Keys on my Desktop and am able to run it just fine (my DayZ character is found and everything). Thanks for the help!
