Run ipython3.exe and it quits with this error:
ImportError: No module named pkg_resources
pkg_resources is a module that ships with the setuptools package. setuptools has been adandoned now, but a fork of it named distribute provides this module. So, install distribute (see how) and this error will be gone.
