delphiace 10 Posted October 9, 2009 When running ArmA 2 I get this message: "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86(32-bit) or x64(64-bit) version of the program, and then contact the software publisher." 1 errors during installation related to unable to install DirectX. I account that to already having that version installed on the system. System: CPU: i7 920 @ 2.67GHz Ram: 6 gb OS: Vista Ultimate SP2 (64-bit) (also same issue under windows 7 (64-bit) Video ATI 4670 chip set w 512mb ram. Thank you in advance!

EDcase 87 Posted October 16, 2009 Have you installed latest DirectX 9? You must install it even if you have DX10 installed. Share this post Link to post Share on other sites
