Follow up:
Getting ready to do that other thing and thought I would back up some files. When I looked into the DX folder, I found three set of some things, two sets of others. So I consolidated everything into only one appropriate folder for each category and deleted the spares. No more problem.
I think what happened was when I did a system restore, it made extra folders and then new updates didn't really know where to install.
Thanks again for all your help..
