Can you please explain how you fixed please?

Hi all, I saw this game and thought it looks great, but I need to buy Arma II and I was wondering if the mod can work with the Anniversary Edition or if you have to only have Arma II and Operation Arrowhead, I'm guessing it will work just want to play it safe. A second question, is it possible to install the game and mod on multiple computers using the same Arma II game (if you understand what I mean, buying the game once and installing it on multiple computers) and then play at the same time? Just a last thought, is the mod worth it to buy the game just for the mod, I mean I'm sure the game is great on its own but I doubt I would have bought had I not heard of the mod. Thanks

Well thanks for all the answers, I'll probably just stick with buying Arma II and OA, just to be sure. And thanks for letting me know about buying another OA, I probably would have found out eventually anyway. Anyways thanks again and maybe see you in Chenarus in the future.

I know that but can the Arma X Anniversary Edition work with the mod is what I mean.
