I would recommend that you re-post to the PyWin32 user's group. They
know the low-down on this stuff.

You can find them here: http://mail.python.org/mailman/listinfo/python-win32

However, if you cannot access the object library, than that's probably
the problem. I've no idea how to resolve that though. The gurus on the
group linked above would likely know however.
