Some thoughts:

1.  From looking at the code, it seems where should be more output (the 
values of "A" and "out" for example.  Can you report those too?

2.  What does "sympref python" report?

3.  Does something like "setenv PYTHON C:\Python27\bin\python" help?

4.  Perhaps you should try the bundle package.

5.  There is more notes on Windows installation here:
