If you are using Vista or higher you can't install content in the Runtime in the Poser directory if you have Poser installed in Program Files due to User Account Control; that's why the default is elsewhere.  The only things that should be installed in the Poser program folder are add-ins such as DSON Importer or Python scripts you want to appear on the Scripts menu

I'd copy that runtime folder elsewhere (perhaps 'C:Poser Library') and reinstall Poser, pointing the content installation to the new folder.  You may need to reinstall DSON Importer...
