The easy answer is to unzip them into 

?:Program Filese frontierPoser 7
?:Program FilesCurious LabsPoser 6
etc.

or where ever your version of Poser is installed

Make sure the folder structure is kept intact.

But the long answer would involve creating extra runtimes to extract the filesinto. This will stop the main runtime becoming to large and unmanagable when you really get hooked on poser.
