The download manager seems a nice touch particularly for those with limited download speeds as you are able to select the whole massive download in small chunks.  Still some big chunks mind but I guess you can expect that with something as complex as Poser. 

You can pause the download so if it fails I guess that you can attempt a resume, I say guess, because I am not going to stop it to find out.

 

 

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.
