About Age of Empires III (2007)
Age of Empires® III (2007) is sold as a collection that bundles three Age of Empires III titles. The description highlights commanding European powers in the New World or Asian factions in their own struggles.

01 / THE GUIDE
Multiplayer Backend Change
Effective September 1 2021 the original multiplayer service for the 2007 Age of Empires III Complete Collection stopped functioning because the ESO domain left Microsoft’s control and will be repurposed.
Players who wish to keep accessing online matches must install a new patch that redirects traffic to a Microsoft‑owned backend before that date.
- Check the official site for the latest patch version before installing.
- Apply the patch before attempting to join a multiplayer match.

Manual Patch Installation
The AgeIIIESOPatch_Full must be downloaded from the official website and installed manually before the September 1 2021 deadline. The installer redirects the game’s network calls to the new Microsoft backend.
Because automatic delivery is unavailable, users need to run the downloaded installer themselves. After a successful install, multiplayer connectivity should remain functional.
- Run the installer with administrative rights to ensure file replacement.
- Keep a backup of the original game folder in case you need to revert.
