I have read the advice about using the inbuilt copy of Python when installing Zope, and confirmed for myself that I don't see how to get Zope to use an existing installed version of Python. But I am trying NTUserFolder which relies on win32 extensions. I have installed NTUserFolder and confirmed that it too doesn't run with the default installation (<Error Type: KeyError; Error Value: PARENT_URL>, when adding a new user; details below - I assume that lack of win32ext is the problem but could very easily be wrong). I would like to know either - how to get win32extensions visible to the Zope copy of python, or - how to get Zope to look at my 'win32all' python installation (which I would ensure to be the latest version of python). As always, thank you for any pointers to a solution.
