Hey iridium21,
just to make sure we're talking about the right thing:
When you say "anniversary edition" are you talking about the History Collection or about something else?
Since you need to activate all Ubisoft games (except very old titles) to a Ubisoft account, you'd only need to download Uplay (https://uplay.ubisoft.com/en-GB), login with your account, and then you can see your library with all your games.
Hope this helps,
Ubi-Thorlof
