Description:
This file will update your Arma 2 installation to version 1.04.


System Requirements:
- ANY ORIGINAL VERSION OF ARMA 2 from 1.00 to 1.03 other than the Steam version, Steam users should use the auto updating feature instead (their game will not be playable if they apply this patch until they recover it again from Steam)
- DirectX 9 March 2009 is required and should be updated during the patching process automatically as needed or you can update your version of DirectX from www.microsoft.com/windows/directx/


Installation:
- Run the patch exe to apply the patch setup automatically.
- It will install all content of the patch to the folder with your ArmA 2 installation (default is C:\Program Files\Bohemia Interactive\ArmA 2 or Bohemia Interactive\ArmA2).
