Pyinstaller - ImportError: No system module 'pywintypes' (pywintypes27.dll)

Question

I am trying to package my python script into an executable. I thought I would be pretty straight forward as I don\'t have very many imports. First off here are my imports:

Answer 1

You should run post-install script for the pywin32 extensions with a '-install' parameter, to ensure the environment is setup correctly.

pywin32_postinstall.py -install

Answer 2

I just copied the DLL pywintypes27.dll in C:\Python27\Lib\site-packages\pywin32_system32.
I added it in win32/lib.

It's OK!
