[Zope] how to install win32com?

Hi all, I need to get my Zope on win32 to be able to use the win32com module, but unfortunately have almost no understanding whatsoever of the windows platform. I've tried installing ActiveState python 2.1 and getting it to work with zope - no joy. I've tried installing the win32all package for python 1.5, but the stupid installer just says "you don't have python 1.5 installed on your computer". Arrgghhh!! Can anyone RTFM me in the right direction? I don't have a clue what I'm doing :-) thanks, seb
