I had installed this in Studio 11 it's an excellent plug-in (if you don't mind looking at their advertisement each time you use it).
To get it into Studio 12 I copied the .chm, .fex, and .xml files to the Plug-ins folder of 12 and renamed the .chm file from "FreeEffectsforStudio" to NewBlueCartoonr.chm and it now appears and works in 12.
