The 1.04 update is now available via the in-game auto patcher and as a standalone update.

Ensemble Studios' Age of Empires III has gained quite a following online, and this latest patch fixes a few network problems and resolves some issues with the in-game auto patcher.

Potential patch installers should be aware that Ensemble are reporting that many user created mods aren't working with the newly updated version of the game, and can cause crashes. It is recommended that users uninstall any mods before updating the game to version 1.04.
