I had problems with some updates (for the German version) in the past and now it happened again.
I started and obviously completed the download of 1.1.3.3 (English version). Then I was told "patch 1.1.3.3 has been downloaded and is ready to install". Well, I clicked on "install" and then the installation process continues endlessly. I stopped when the number had grown beyond 60000/3.
I followed these instructions:

So finally I decided to install it manually: I found where the update is stored, extracted the three packages and copied the content to my Skyrim folder. Then I manually set the current version in the config.sur to 1.1.3.3 (I just don't know what to do with the line iCpDate ?)
Everything works now but this is not how it is supposed to be done, eh? Any suggestions for users with the same problem?
