The Custodian 4 software download is the full version but runs as a trial until activated with a key. The trial version is limited to ten records per data form but you can try it for as long as you like. If you wish to purchase a key for full access, please use the How to Order page.

Custodian 3 users: If you need to transfer data from version 3, select “Install Components” during the installation routine and tick Migrate, then continue with the installation. Migrate will only work with a purchased and registered version.

Updating your version 4: to update your current version, download the trial version and ensure you install it in the same location as your original installation. You should not need to re-enter your key unless you are updating from a very early version of 4. Always backup first, though the update will not touch your data. Information on What’s New, itemising changes is now available from here.
