Caution technical problems

Unfortunately I can not install the game, because the installation hangs.
Although you have to register with a Ubisoft Uplay account, technical questions, however, operate as not. When I tried an inquiry, I ended up on the formulation of my problem in a window with multiple links that have been suggested to me as possible solutions. Unfortunately, this did not meet the problem, I could, however, only a button with 'My problem is solved' click and my request was accordingly not sent to the support. So you can save the tevchnischen Support obvious ....
