Download and install the latest version of Artisan.
The installer, on a MAC or PC, will first remove your prior version but this won’t remove your prior settings if you have them. You can also downgrade to a previous version by just uninstalling the current version and re-installing the old version without losing any settings.
To ensure no issues, save your stable settings before changing any settings or installing a new version (Help>Save Settings).
More complete instructions on the Installation page.
