Pip Error when installing

Whenever I try to install pip usin the get-pip.py script, it just gives me errors. Ran cmd as Admin, re-installed python already..

I'm using python 2.7.9

 Exception:
  Traceback (most recent call last):

Ok, It was indeed because of the "ä" in the name, changed the user and it installed fine, thanks to Padraic Cunningham for pointing it out.

Just for the sake of completeness, in this case the problem, as pointed out by Padraic, the problem was the non-ASCII character in your username. A similar error would have occurred if you had had non-ASCII characters in your computer name. So, for you poor souls finding this, be ware of that :-)
