from distutils.core import setup
import py2exe

    name =

There is a similar issue here: https://github.com/ContinuumIO/anaconda-issues/issues/37. I see you use Anaconda, and I think this is an issue with anaconda and the python interpreter.

Essentially, the issue is not present when using the IPython interpreter instead! Try for instance:

C:\...\User> python
>>>import pythoncom
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\Program Files\Anaconda3\lib\site-packages\pythoncom.py", line 2, in 
    import pywintypes
  File "C:\Program Files\Anaconda3\lib\site-packages\win3\lib\pywintypes.py", line 124, in 
    __import_pywin32_system_module__("pywintypes", globals())
  File "C:\Program Files\Anaconda3\lib\site-packages\win32\lib\pywintypes.py", line 98, in __import_pywin32_system_module__
raise ImportError("No system module '%s' (%s)" % (modname, filename))
ImportError: No system module 'pywintypes' (pywintypes34.dll)

On the other hand, try

C:\...\User> ipython
In [1]: import pythoncom

In [2]: pythoncom
Out[2]: 

No problem when using IPython!

Son until this gets fixed, you can run your troublesome .py files using the IPython interpreter instead, eg:

C:\...\User> ipython setup.py

and that should work. You should seperate arguments you want to pass to your script from the command by a --, otherwise IPython might attempt to parse it, eg use:

C:\...\User> ipython setup.py -- arg1 arg2

Until this is fixed, try this method.
