Reviewing your previous posts, It looks like you not only installed to "Program Files" but also the main Poser runtime.  This is not good.

Content does not go in the main Poser library, it should go to a content folder.  Some people choose that horrid "MyDocuments/wholebunchofstuff" default.  I just choose a descriptive name, like "PP210content"

Installing anything to "Program Files" will give way to annoying problems with the UAC.  Most people recommend not disabling UAC, however it will cause problems if you need to write to there and hides files in virtual store locations.
