I looked and only become more confused for a course of action. I looked at the definition of nested and my interpretation is intertwined . I have thought previously installed  content had to be somewhere.  There seems to be a couple shortcuts that lead to the same places or slightly different leading me to think multiple layers of install.

I can see data file folders and components possibly two different data folders.

Unless you have a better idea I am thinking nuke it all and reinstall.

If the big delete is to be used I would prefer suggestions as to how to construct the Daztime for the best result please.
