That's true, and distutils on Windows gives no choice about this (the
installer was built via the distutils bdist_wininst command).

I'm guessing you didn't run the alpha 1 uninstaller first (one was created
by the alpha 1 installer, and an entry for it was created in Control Panel's
Add/Remove Programs applet).

That's not enough (as you already discovered <wink>).

One of the *other* things the alpha 1 uninstaller would have done for you is
remove these files from your *Python* directory's skel/ subdirectory.
That's where those .zcml file are really coming from, and they'll keep
coming back every time you run mkzopeinstance.

On Windows, people will just have to live with needing to run the
uninstaller for the previous version before running the installer for the
current version.  That will remain the case until "a real" Windows installer
can be written; I don't know of any plans to do that (whether in or out of
Zope Corp).

BTW, thanks for trying it!
