An official patch is now available for Age of Empires III: Complete Collection!

The AgeIIIESOPatch_Full will allow you to access multiplayer services without routing through eso.com. This not only removes a major obstacle to playing in online matches, but provides additional stability and reliability in the multiplayer environment.

You will need to download and install the patch manually from the official ageofempires.com website: https://aoe.ms/aoeiiipatch

If you experience any issues downloading or using the patch, please reach out to our Support team at aoesupport@microsoft.com for assistance.
