[2020] Uplay won't finish the download

Have you tried pausing and resuming the download again? Perhaps, uninstalling the game and reinstalling again?

If you continue to experience issues while downloading the game, please contact our Ubisoft Support for further assistance. Thank you!

Hey PL3X Sarpolex, have your friend try these steps and see if they help with this issue.

Hey Cthulhu1512, and welcome to the forums

Making sure your connection is set up correctly for Uplay by going through the steps listed here (Especially the part about port forwarding) will usually resolve this issue.
I would also advise launching Uplay with Admin rights

Thanks for sharing your fix redwolfao.
