The elements of the path don't have names - they are a list of
directories. You are mistaking Pythonwins configuration options (like
where it searches for modules) for the python path.

Note that the registry entry "PythonPath" (which is not respected by
Python, but used by Pythonwin to override the default python path) is
a semi-colon separated list, not a series of keys.
