My mistake, I forgot to add the required dependency "patsy" to the package 
list. I'll fix this in the next release.

In the meantime, you may install patsy using the WinPython Control Panel:

1. Download the 2.7/64bit version of patsy here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#patsy

2. Execute the WinPython Control Panel

3. Drag an drop the installer downloaded at step 1 and click on "Install"
