If the morph packages do not include a Poser Core File (PoserCF), then you install the files within the DAZ equivalent of Poser's runtime folder, in this case, My Library.  I believe the core folder is entitled 'Data'.  This is the only way Genesis/Genesis 2 will recognize and load associated morphs with the DSON Importer.  Unfortunately, though, when searching the Parameter/Properties window for your new morphs, it may take a little time to locate exactly where their nested.  I find that intimidating if there are too many morphs loaded into one figure.

The best way to install DAZ DSON files is using the DAZ Install Manager (DIM) which removes the core content folder automatically and places everything where they belong.  Otherwise, manually decompressing each folder and moving them to their appropriate places can become very tedious.
