How do I update?

Download the full package, launch it and then follow the instructions on screen. For full installation instructions, please see the Installation Guide.

Install further packages in date order (oldest first) or enable Live Update once the full package has been installed.

Do not deinstall previous versions, as you may delete your database in the process.
