babun won't run python3 on win10

Question

I am building a new Win10 machine. I have babun installed, and im trying to get python3 running. Problem is it won't execute.

$ python2 --version
Python 2.7.8
$ python3 --version
$

any ideas what would cause this? or how to debug it?

output of debugging. It looks like everything is noise, but im not sure.
