The SACD module can be imported on a machine without Python installed and
it's working.

The application is shutting down since SACD can't be imported.

Nope, printing sys.path showed that all the "regular" Python path is in.

This is *not* a python script wrapped with py2exe. py2exe was
used only to find the dependencies and create the zip file (which was
renamed to python23.zip).

I've found out that if I remove the _sre.pyd and the zip library everything
works on a computer with Python installed. However I'm still in the dark on
how to solve this.

Thanks for your time.
