The write access calls occur when typelibs are added to the scripting ActiveX :
pythonEngine->AddTypeLib( theLibGUID, dwLibMajorVersion, dwLibMinorVersion,

This should not be the case, and there should be no assumption about the
location of the typelib - indeed, we generally just ask COM to load it for us.
I'm afraid I have no insights to the problems you face, so you might need to
dig a little more to see what is going wrong, or work out a way so I can
reproduce the problem locally.
Cheers,
