I installed the free EQuivocate plugin, and then the paid bundle. I never installed the demo of the bundle. The installation process of the bundle did all of the work. The EQuivocate license now shows up under "All" and "Unavailable".
Note that the H910 Native license is unused, since that plugin is part of the H910 Bundle I purchased some time ago. It came as part of the PreSonus free plugin suite for owners of any audio interface. I picked it up because it was a bundled installer with 2016 Stereo Room. I was happy to see that the licenses were separate so I can update 2016 Stereo Room separately.
