Failed to upgrade pip in fresh 2.7 install

[paul.hermeneutic at gmail.com]

After a fresh install of Python 2.7 32-bit and 64-bit, upgrading pip
using pip fails. Am I doing this incorrectly? Any suggestions?

C:\Python27-32\Scripts>pip install --upgrade pip
You are using pip version 7.0.1, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
