[Zope] Zope and Windows

Have got Zope 2.5.0b2 installed on Windows 98 and have had no problems so far. However, I notice the version of Python that is used is 2.1.0 I have ActivePython 2.2 installed, how can I get Zope to use that version of Python instead of the one it ships with? I have modified the startup batch file to read: C:\Python22\python.exe "C:\Program Files\WebSite\z2.py" -W:9800 But that does not seem to work Any ideas? I have also seen the file pythonw.exe as well as python.exe, what is the difference.
