When I just started Minecraft, it tried to update onto newest version 1.11.2. The Launcher updated alright, but when I tried to start, the Launcher tried to update Minecraft itsself and it crashed on one of the last jars. It shows "...0209-natives-windows.jar" on the bottom and an almost full progress bar and then crashes. It shows "SPIELABSTURZ - Ein unerwartetes Problem ist aufgetreten und das Spiel ist abgestürzt.". I tried to update Java, didn't work. I tried to deinstall Minecraft and reinstall it. Didn't work. Then I deinstalled Minecraft and cleaned all the remains like the ones under "AppData/Roaming/.minecraft" and reinstalled it again to get a clean fresh Install. But the problem is always the same, as described above.

The launcher report says:
