Reverse Engineering of Windows Distribution

[Markus Stenzel]

The exe was compiled using py2exe. I have identified a set of well known 
initials "PK" (Phil Katz, author of the legendary PKZIP software) - and 
in fact there was a ZIP embedded in the executable at position 9000C.

Unpacking this zip resulted in a bunch of .pyc files which I'm currently 
running through the beta version of the decompyle package. Wonder if 
that will work ;)

Thanks for your help Peter.
