I thinks its best not install to the content folder inside of Studio.  I prefer creating external runtimes and content.  The two main ones I made are "PoserStuff", for Poser format, and "DAZStuff", for native Studio format.  I also a "PoserDummy" and "DAZDummy" that I install everything to first.  This way I can rearrange or fix things.  If I needed to rearrange or fix  the  folders or files  I re-zip  and archive along with the original zip or installer.
