Not sure what the question is, but I just updated to 2015.1.1.
I just looked in help/updates, and there is was, so I hit it, and the update went through no problem. I had been intending to do it foe some time, but had not got around to looking for it, dealing with authorization codes etc..... So when I saw the update link, I went for it.
Took maybe 35 min and most of that was because I was doing other things and didn't check in it very often. Didn't ask for any codes or numbers, no uninstalling, etc, it just did the update without a problem.
