If your OS is Vista, Win 7, Win 8, Win 8.1, or Win 10, no content or figures should be installed into Poser, especially if it is located within the Program Files folder. Python scripts are exceptions. PCFs can be installed anywhere as long as their runtimes are linked to the Poser Library. My advice for installing DAZ PCFs into Poser, use the DAZ Install Manager (DIM). Those particular files, including the DAZ Core Files, have a different, additional main folder which is stripped out when using DIM. Otherwise, manual installation would require decompressing the file into a temporary folder then moving the content into their appropriate folders.

And BTW, there is no such figure as Genesis 1, just referring to Genesis is enough to get the point across.
