Lost Product Key

I was trying to install Age of Empires Titans Expansion on my computer, and I dont have the box of the product key. This game was installed on my old computer without any issues, but the box split after being dropped and I put it in a new CD case. After that I wanted to install it on my new computer but cannot get past the cd key installation window. Can anyone tell me how to retrive this games cd key? Thanks

I think that you should call Microsoft and they will be able to help you out. Below is the link of microsoft where you can get the phone number:
