Trouble running on Windows with EPD7.3 64, Canopy 64

On Windows I tried to get this going with the EPD7.3 release and the Canopy 64 release. If I open a command window, neither `python necofs_models.py` or `python enaml_gui.py` is working. Here's what I get:
1. For necofs_model.py:

c:\Users\rsignell\Documents\GitHub\NECOFS>python necofs_model.py
Traceback (most recent call last):

2, For enaml_gui.py:
