So after many restarts and reinstalls I have now reached the point where I have uninstalled Poser 13 and any lingering information, downloaded and installed the latest version of Poser (13.0.339).  The install was placed on a drive other than the system drive and I checked to have any exiting preferences removed but Poser 13 still does not launch.

 

 

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.
