Dear Dennis Just installed Zope 2.12 with 32-bit Python 2.6.5 on Windows 7 (64 bit). Did not encounter any problem, except that I had to remove the logging to Windows events in zope.conf; otherwise it would do nothing unless run with admin privileges. However, we do not use the full power of Zope - just some basic functionality, but I wouldn't expect problems, Because Python runs just smoothly. Later this year we plan to tackle 64 bit. Best regards, Martin
