How can I play Age of Empires III online? Keeps saying invalid key code


I bought AOE III at Amazon and got invalid key code, got one from Walmart and got the same error so I returned the one from Amazon and got a 3rd disk and got the same error. I contact Microsoft and they tried everything but said looks like its the creators issue and I have to wait for them to resolve the issue but looks like there still may be good key codes out there. Tried download online too and saw they were having same issue, like there is bad batch of key codes out there. Does anyone have a old valid key code or how I can get online?


Hello, you need to buy the digital version on Steam, that is the only place where the game is officially distributed nowadays with valid CD keys pretty much ensured:


See notice on 04/30 and then I saw comments in August asking when they were going to resolve. I just want to get online. I use to play this game 10 years ago. Does any one have extra game or code?

The issue mentioned there lasted for one weekend in April.
