When updating the product, you should always copy the license files
from lib/python/mx/ODBC to a safe place and then remove the directories
lib/python/mx and lib/python/Products/mxODBCZopeDA *before* installing
the new version of the product. This is needed to make sure that no
temporary files or byte code files from a previous installation are
left over and mix in with the new files.

After you have uninstalled the product that way, unzip the new
archive and reinstall the license files.
