There is no information about this add-on or its whereabouts. No website is provided to gather the information about it. If you still use Eloquence Author, then you should contact the developers and ask about Cincom Genesis. It's possible that the add-in is used for a totally different thing, but since it has "authoring" in its name, I can say that it makes it easier to use it with a certain application and the authoring process.
