This may seem after the fact, the only software that I found convenient for installing and removing content completely, provided that content had not been moved or relocated, is Ahudson's 3D Content Installer.  Installation from zipped content, it generated a text file which tracked all content and pathways.  The beautiful thing about it, take the text file and drop it onto the built-in uninstaller and it would remove all traces of your installation.  Unfortunately, it was never updated after P7, and it is no longer available.  Quite a shame, nice software.
