Hi 
Since these files are for Poser users,. the intended install location is wherever you install your poser content.
it should then show up in your poser runtime.
depending on your system, the poser version,. and the choices you make when you install Poser, the runtime libraries can be in several locations,.
On a Windows system, it could be Users\Public\Documents\Poser Pro 2012 Content.
Once you’ve installed the Genesis Starter Essentials for Poser,.
you should install any Poser companion files for products, into your poser runtime.
Then you can access them in the normal way in Poser.
Hope it helps
