Windows installer doesnt ask for permissions, then crashes
I just installed pandas on my "new" Windows 8 system using pandas-0.9.1.win32-py2.7.exe and had some trouble doing it: Python is installed to Program Files\Python27 (nothing unusual I think), so the installer needs admin permissions to write.

The installer didn't ask for that permission (no UAC), instead it crashed without useful explanation:

Starting the installer as administrator solves the problem.
