Muse Research, the owner of KVR, has released a special "User Installable" installer for Zero-G's Nostalgia which enables Receptor owners to install and authorize this plug-in on Receptor.
You must already own, and have access to, the original version of Nostalgia; the installer prepares your Receptor to receive the data files from the original DVD, and installs Receptorized patches for the plug-in's presets.
