Step 1: Navigate to the Nicolesy Watercolor Effects.ONPreset file on your computer.
Step 2: Right-click the file and choose to open the file with the latest version of ON1. (Note: If you have more than one version of ON1 installed on your computer, double-clicking the file oftentimes installs it into an older version of ON1, so right-clicking is the recommended process.)
Step 3: The presets will automatically be installed and can be accessed in the Presets panel on the left.
