I bought it and can't for the life of me can't understand how to apply it to a prop.

I've tried attaching it to an object and I've tried selecting an object as a parent from the modify tab.  I've watched Reallusion's tutorials on Particle FX and it's clear that this one is a bit unique.

Any one have any insight into how this works?  This will be crucial to a project I'm working on and I'd be grateful for any insights.
