OK so that means that means Poser now knows where your runtime exist so under normal circumstance that should be all you need do do. What information is Poser giving you in the library.

Any of the tabs should show all the content folders in the runtime, the number in brackets indicates the subfolders for each content folder so as you can see in the picture the character tab shows all the content folders. I have selected the roll down on the Dawn tab which now lists the 71 subfolders for character content in the Dawn runtime. Clicking the roll down on the Coflek Gnord shows the two subfolders for my Coflek Gnord content, Cyber Headsets and Exploding Collars and each one has two items.

Are you seeing the same sort of layout, if you are then icons are actually a representation of the files you need. If not then there would appear that your runtimes backup is incomplete they have not been transferred correctly.

If the runtimes are setup correctly this is what the listing should look like in Windows and this is what Poser expects to see.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
