Do you have Victoria 4 installed in DS.
Any “Pre Genesis” daz3d models, should come as Poser format, with perhaps DS shaders ,..
When you install any of these, they will create the Runtime folder if it’s not there already
If you install V4 into Daz Studio,. it will create all of the “Runtime” / Figures /Poses etc ,.
If you don’t have Poser, or Daz Studio,. and you want to use Daz/Poser content in Carrara, then you can still do that because the products like V4 will create the folders they need, when you install them.
DS Pro doesn’t need a serial number now,. since it’s free it’s easier to deal with if you’re not handing out serial numbers.
