How can such a thing be?

I've wanted this game as a gift, the negative reviews I've read and thought to myself, I will not make any technical problems.
And that was thought dead wrong! After I inserted the disc there was no such mention in the description "you are asked whether you want to install DirectX ..." question but it was easy to install. Well, that's not a problem. But after everything has been installed and even online registration requires, for not opened up to me the meaning. But you can make quite a lot with it. Now we go, thought I- but it was nothing, the game just did not start. Also the guidelines presented in the manual does not. So I searched the internet and found answers-try that out, Try this out. But what is the nonsense? If I buy a game and I have a new technically flawless PC meets all the conditions, I simply expect that the game without turning off virus scanners etc. programs installed on my PC works! Other games puts you on and they run fine.
I once played like Anno, no longer! If Ubisoft wants its customers away, please! For me it has in any case already worked!
