[Zope] Installation of pyXML

Hi, where and how I have to install pyXML for the Product ParsedXML? I use PyXML-0.7.1.win32-py2.1.exe for Zope 2.6 and Python 2.1.3. In this executable I can't set the installation directory. Do I have to install Python in a different directory as a seperate software? The product ParsedXML nedds this library. Thank You for help Fritz
