When I first launched DLM I had a message saying there was an update.  It is now at 10.4.27796 but I did not update to SR4 as such as I purchased the game version.

Now when I launch DLM I have the Installed list and also an update tab in the top left hand corner.  Under that I have the two new updates listed.

Appears to have updated fine and having run my normal basic tests like rendering loading saved scenes I have no issues so far.

 

 

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.
