Hey SirCryloc - welcome to the Ubisoft Forums!
All of your Ubisoft Store purchases are permanently associated with the Ubisoft Account used. In terms of PC games, they are added to your Uplay library and remain there for you to access.
You would not be charged again to install the game on another device, as you have already purchased it.
Hey there phase.verocity!
You should be able to download Ubisoft Connect, and any games within the library, on two different computers at once. You may not be able to launch them both simultaneously and play the game on both computers at the same time, though. You will only be able to play any games on one computer at a time.
I'm confused by this, "You SHOULD" be able to download ubi connect and any games within the library on 2 devices at once, how are you meant to do this "at once" if you can't launch them both simultaneously? (Presuming you mean can't launch both copies of ubi connect) your userbase has been wanting to be able to log into their accounts on multiple devices for years, I was hopeful when I read your reply at first, but I am unable to have 2 computers logged into my account at the same time, I'm not making a second account and re paying for my games just for ease of access.
