I had the same experience. Installed OK but as soon as I fired it up crashed to desktop.  That was just after it had become free again.

I later built a new computer, the specs are below and, more out of interest than anything else I tried again, same thing, install, start, crashed to desktop.  Everything else works fine with the exception that recently Luxrender would bluescreen when going render via GPU.  No such problem with CPU.  Otherwise a stable system on all except Daz Studio, I have no idea why and was afraid if I changed too much it would screw up other programs. 

As I work in a computer repair shop, when I get home I like to render not play with PC configs so I gave up.

 

 

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.
