Well, Ive come across a Weird issue, and Ive had a good look around the internet, and found nothing. This problem involves the Steam version of Arma 2 & Arma 2: OA (The Arma 2 CO Pack) Basically, I Launch Arma 2, or Arma 2 CO, then I get the "First time setup", After the setup nothing happens at all, Nothing appears at all, Ive taken a look in my task manager and nothing has shown up in there either. I'm currently Windows 7 64-bit with a Nvidia 450 GTS (SO Edition). No errors pop up at all, Although when I verifiy Game Cache with steam it does say 1 file is missing (But apparently that's normal) Does anyone know how to solve this issue without reinstalling Arma 2 and OA (Took me around 5 hours to download them both). Looked on many Forums and tried many thing to get this to work, Nothing has helped me at all... Apparently this is a Big issue which many people are getting, yet there is nothing posted on how to fix it. Also seems to only happen on Windows 64-Bit Update: Uninstalled Both, Then Just installed ARMA 2, Still doesn't work Before you say it, Running steam and the game as admin doesn't work for me.

No, Just deleted the file then Re-Ran the Installation for DirectX The Problem has been fixed Just had to delete XINPUT1_3.dll and D3DX9_41.dll from System32 and SysWOW64 and works fully now, the game works, that's the main thing :D

Still not working, Downloaded and Verified it many, many times UPDATE: Fixed the First issue with the game not launching, Just replaced D3DX9_41.dll NEW ERROR: Here's a screenshot
