I bought Arma 2 OA, downloaded and installed it. But everytime I try to install Patch 1.60 and 1.62, I get that message while patchin (at some files): xdelta3 returned error code: -1073741819 I used Patches from different sites, reinstalled the game, nothing helps. Afterwards, even though I get these errors, the patcher tells me that the patch was succesful. My System is: CPU: Intel Core i5 2500k Ram: 8GB DDR-3 GPU: AMD Radeon HD 7870 GHZ Edition OS: Windows 8 64 Bit Any help what I can do so the update works? I also can't get on DayZ Servers. Here are the errors:
