Depending on which version of MySQL you are using, you will need different drivers.
For MySQL 4.0 - you need MyODBC 2.5 drivers, downloadable here:
For MySQL 4.1 - you need MyODBC 3.51 drivers, downloadable here:
Please
note: for MySQL 4.0 - you will also need the 3.51 MyODBC drivers on
your server if you want to create a DSN. This is because 2.5 is used by
Helm to create users and databases, but 3.51 is used for the DSN
connections.
Also ensure that the root user has ‘root@%’ privileges rather than ‘root@localhost’
