1. Once the file has been downloaded, locate the installer.  It may be stored in your downloads folder or desktop depending on how your web browser is set up.
2. The installation is managed by the Radiant Manager. 
3. Make sure any image editing applications like Photoshop or Lightroom Classic are closed. 
4. Use the appropriate installer listed above. For macOS, be sure to choose the correct version based on your processor type.
5. Launch the Radiant Photo installer.
6. After accepting the End User License Agreement, the installer will start.  If you purchased the Radiant Photo plug-ins, the installer automatically attempts to locate all installed versions of Adobe Photoshop, Lightroom, Classic, or Corel PaintShop Pro and then installs the plugin for all these products.
7. The activation is managed by our Radiant Manager.  After accepting the End User License Agreement and entering your system password, the installer will place the Apps Manager in your Applications folder.
8. The AppsManager should launch automatically after installation.  If not, navigate to your Applications folder.  Open the Radiant Imaging Labs folder and then launch Radiant Manager or simply search your system for Radiant Manager.

After the installation, please reboot your computer for the best results.
