Dawn of War International Patch 1.3 [Release Notes]
TBA

Alternatively, enter the online lobby of Dawn of War. Once logged into GameSpy, the patch should automatically download and be applied to your game.

Note: Patch 1.01 is required to patch to 1.10, which must applied to your game before you can install Patch 1.20. This shouldn't be an issue for people autopatching through the Online lobby.

If you have changed data in your game – due to modding, for example – you may have to reinstall Dawn of War and reapply all patches.
