Dear all I'm trying to install Zope2-2.12.0b2-py2.6-win32.egg on Windows. It's the first time I try to install an egg, so I may have made a trivial mistake. The installation installs some packages, then tries to install zope.security, and fails with a missing vcvarsall.bat. I haven't got a C compiler installed - I assumed the purpose of the Zope Windows egg was that I wouldn't need to compile?
