A customer running my software, distributed via py2exe (Python 2.7.2) is
consistently getting the following error

from wmi import WMI as WMI

prior to obtaining the details of an attached USB flash drive.

It has been confirmed the error is specific to that particular machine
(running 32 bit Windows 7, I believe). Has anyone come across this problem or have any suggestions
please as to probable cause and, of course, solution?
