Lumenzia 11.5.2 - Mac+Win

Quick question - When I try to install this I get a message saying no compatible versions, but I have the appropriate version or higher. I tried a manual install extracting the ccx and putting it in the plugins directory ala TK8 but that didn't work either, nothing is recognized (although tk8 is). Thanks in advance if you have any insights.

EDIT - Just FYI, tk9 installed just fine, so I don't know what the deal is.
