I bought my game from Amazon, brand new and sealed; when I install it, says I have version 1.03. So far I have downloaded the 1.05 patch from 4 different locations and every time I get the same error 'Arma 2 Has Stopped Working'.
Been trying to get online to play multiplayer and getting many messages stating my version is too old when I don't patch it. I have uninstalled the game several times as well and it does not help, so basically the 1.05 patch is not working on Windows 7 64bit. The game plays ok without the patch, but then I struggle to get on multiplayer with 1.03. The multiplayer was recommended to me, but I am sorry I bought this game now and I will leave negative feedback on Amazon as a result, the tech support for this is almost non existent and I definately won't recommend the game to anyone else.
