If an update is available, the Radiant Manager may open and prompt you to update your software. Up to once a day, your plugin will check in to our website to see if an update is available. If there is, the Radiant Manager will launch, and you’ll be prompted to run the update. Click the Update button next to Radiant Photo to start the installation.
The Radiant Manager is the fastest and easiest way to keep your application up to date. Updates can include enhancements and bug fixes, as well as new features. Just follow the on-screen instructions.
Make sure to quit any host applications such as Photoshop or Lightroom Classic as well as Radiant Photo when running an update.
