Recently I have installed the ArmA 2 in my Windows server 2003, 64 bit computer. The game is capable to run in this computer. Now I have got a latest patch for this game and that is of version 1.57. This patch was installed in the computer properly. Then I tried to install another new patch that is of version 1.59. The problem is it cannot install in the server. No matter what I do it just it keeps on showing me a message like " ArmA 2 OA is not installed on your PC otherwise the installed version is incorrect". What should do now? How can I install this patch?
