I think I figured it out ---all the files are showing paths in the ICONS folder in the registry. Since it's a different new PC if any part of the path is different, I had to do a Find and Replace so the new path (in this case re-directed Desktop folder to a new Server) matched properly.
Anyway, that's how I fixed it: exported Icons reg folder, Find and Replace All for the paths, then deleted original Icons folder and merged in the new corrected ICONS reg folder.
