How do I activate my RC-20 lifetime license?

Once you've completed the Rent-to-Own program for your RC-20 plugin, Splice will email you a copy of the serial number to the email associated with your Splice account with a link to register it at XLN Audio's site. You'll then download the XLN Online Installer and Reinstall RC-20 via the XLN Audio Installer. You no longer need to have the Splice application running or an internet connection to use your RC-20 plugin.
