You ran dependency walker on which file?

How are you running this?  Are you running it from a command line, or
from inside an IDE, or double-clicking on the desktop, or what?  Which
version of Python?  Remember that, using Python 2.4 as an example,
python24.dll and pywintypes24.dll must be present in the DLL search
path, and that the environment variables for a proess started by
Explorer are not necessarily the same as the variables for a
command-line shell.

Is it possible you have multiple copies of Python installed, and that
the Explorer file association is pointing to the wrong one?  If you go
to a cmd shell and do "assoc .py" and then "ftype python.file" (assuming
that's what assoc said), does it point to the path you expect?
