The problem was getting any database adapter (at all) to work with zope 2.7 on xp (Unfortunately I have to use xp for this install - all my Linux installs work great.) However, i have solved the problem and seeing that I found it difficult to find any guidance, I thought I would post the solution. 1/ Install python2.3 2/ install zope2.7 and create a zope-instance 3/Get the ZMySQLDA adapter from zope.org and place it in the products directory of the zope-instance 4/ Download the MySQL-python .exe for python2.3 from: https://sourceforge.net/project/showfiles.php?group_id=22307&release_id=1028... 5/ Install this .exe which puts new files in the python site-packages directory just installed (it would have been empty before this install) 6/Copy these new files to the new zope2.7\lib\python directory 7/Restart zope regards garry
