Hi ya You have confused my by saying Poser/Daz. And I don't have enough information to give you minute step by step information..... IF you are using Windows AND you really did mean Poser.... Are you comfortable having two windows open at the same time on your machine?? If so... Find your Poser Runtime.
It should be in something like Program FilesSmith MicroPoser Pro 2014 Inside Runtime, You'll see a bunch of folders....
Geometries, Libraries, Textures, Python, etc.... Now, Go Back up one lever so you see Runtime. There may be other folders beside it. Now, in another window, go to where you downloaded your new toy. Double Click the Zip file. it will open up and show you Runtime & Documentation if it 's a current file from Renderosity. Select both folders and drag them from the zip file and drop them into the folder that contains Runtime. Repeat if there is more than one zip for the product. ONLY the Documentation folder items will over write.

Good luck!! Andy!
