win32ui DLL Load Failed

I have a python executable that's failing to load on a user's machine
running Windows XP. My developer machine is also running Windows XP. I
have determined that it is failing when it attempts to load win32ui.

I have Python 2.6 on my developer machine and am using the pywin
support (Mark Hammonds???) for Python 2.6.

In order to make the problem smaller and more managable I created an
executable (with pytoexe) of a 1 one-line python script which does the

import win32ui

Running the one-line script on my machine from python source as well
as from the executable created from the one-line source works fine on
my machine. But when I attempt to run the executable on a target
Windows/XP user machine (without Python) it fails with the following

Traceback (most recent call last):
  File "", line 7, in <module>
  File "PrintImage.pyc", line 1, in <module>
  File "win32ui.pyc", line 12, in <module>
  File "win32ui.pyc", line 10, in __load
ImportError: DLL load failed: This application has failed to start
because the application configuration is incorrect. Reinstalling the
application may fix this problem.

The only thing I can think of regarding the difference between my
machine and the target machine is that I have the .NET framework on my
machine. Is it possible that that is the problem? Running Depends
didn't get me anywhere. I would appreciate any help you can offer.
