Activating a product on Uplay : Example with Assassin’s Creed III.
Uplay Download manager: http://uplay.ubi.com/en-GB/ Click to download
Once you have purchased your game, you will have to use a launcher to download the game. After the download is complete, you will be redirected to the Uplay website where you will have to enter your CD key.
If you want to uninstall your game, you will be able to download it again directly via Uplay.
We tested the platform for you and it turns out that yes, it is possible to add a game toUplay by buying a key from a cd-key store. However, it is impossible (for the moment at least) to activate the key in Uplay then download the game, it is important to pay attention to two things.
First: You should order a key from a cd-key store that allows to download the game
Second: You need to select a game that is ” Uplay compatible”, not to be mistaken it is recommended to choose a game from the list of available games directly in the software. It is evident that with Uplay there is no more problems to uninstall and reinstall your game as much as you want… No more DRM !
By following this procedure, your game will be automatically added in Uplay after installation and you will only have to enter your cd-key when you will try to start the game for the first time to activate it.
