Hi guys, new here, looking forward to play this mod. But sorry for the post but couldn't not find a topic here. I already have the Arma2 but is a physical copy non steam. If i purchase the Operation arrowhead on steam, will the mod work? I don't know if the game will install properly since steam use different folder. tks in advance.

any other players having the same experience??? Im about to buy, just dont want to waste £8,00..
