The Problem

Within site-packages/py2exe/samples/extending/setup.py

(line 54 ff..)

# arguments for the setup() call

test_wx = dict(

zipfile = r"lib\shardlib"

options = {"py2exe": {"compressed": 1,

The Error is within

zipfile = r"lib\shardlib"

it has to be

zipfile = r"lib\shardlib.zip"

I stumbled upon while trying to include win32com.client - that module was not able to find gen_py/init.py
