I've been running into the same problems. There really needs to be a standardized, across-the-board way to install content in both DAZ and Poser in such a way that people, especially newbies like me and perhaps you too will not have to go through so much frustration & hair pulling.  I use Photoshop and other editing programs, and have for over a decade now, and I don't recall ever having so much frustration whenever I wanted to install new content in PS such as new filters, actions, and plug-ins. A few clicks and no muss, no fuss. It just gets it done. Piece of cake.

But with DAZ, and worse yet, Poser, you try to install something and files for something like a hat, or hair, or a single necklace get scattered all over several different folders and embedded 6-8 folders deep in the deep recesses of one big Runtime folder. And when you try to load something onto your model, you get a "Cannot locate file..." message and trying to move the right files, like .obj files, etc into the correct folder inside 3 or 6 other folders ends up being a giant 3 dimensional puzzle project. So yeah, I've been there.  Plenty! Including the past 24 hours!
