Did you check if this could be the case?

Generally, there is os.path.join() IIRC which does this portably. This
probably doesn't matter though. What I would check is firstly if this file
could be opened at all, e.g. using os.stat().

Same error? See my initial guess! As a tool for finding out if there are
missing dependencies, take a look at http://dependencywalker.com

BTW: No need to CC me, I read your initial request here, I can ready any
follow-ups here, too. ;)
