You can install Zope on windows in two ways: With an installer, and from source.
Installing Zope with an installer
All final Zope releses also come as a Windows installer. They are downloadable at http://www.zope.org/Products . Download the EXE and run it, and follow the instructions.
The Zope installer includes Python and precompiled binaries of all c-modules, so you have no requirements for these installers, except Windows 95 or later, an IP address and some space on your hard disk.
Installing Zope from source
Installing Zope from source is necessary if you don't want to use the Python version included with the installer, or if you are doing Zope development. Also, since Zope includes C-code you'll need a C-compiler. Instructions can be found at... ?
