Hectic schedule, sorry.

IIRC, when Poser is first installed, you are given 4 choices to select from as to where to create a content runtime for all your purchases and freebies. As least 3 of these options will place the content runtime in other places away from your Program Files folder which is protected by UAC. UAC will not allow reading and writing to the Program Files folder, that is why you should never place content, python scripts being an exception, into the main Poser runtime. I have Win 10, upgraded from Win 8.1, and my content folder is located under Users>Public>Documents>PoserPro 2014 Content. PP2014 is my version. If you are not sure where your content runtime is located, open Poser 10, go to your Library and navigate to the top most runtime at Show Library context menu. For you, that runtime should be called Poser 10. Hover your mouse cursor over the folder name and you will get a path popup as to where your content runtime is located. You install your content there.
