What I am seeing is the creation of subfolders within your Poser folder which does not work very well. You are creating a runtime within runtime, libraries within libraries, etc. To make easy on yourself, go to the top level of your Poser folder, go back to your zip runtime folder, highlight and drag to the Poser folder itself. Not to the runtime folder. When prompted to overwrite, click OK.

Now, which OS are you running on your computer? If you are running Vista or greater (Win 7. 8.1, 10) then you shouldn't be placing any content into program files/program files (x86). Windows UAC will interfere with content access and place your actual content into a virtual location. The default installation for DAZStudio/Poser should be in a Public Document folder away from program files folder. I'm pretty sure this is complication your installations. And this is based on the screencaps you provided.
