Can't install Premiere Elements 4

I've tried at least five times to install PE4 to my laptop to no avail.  Each time, the same error occurs and the whole thing backtracks.  I've tried copying the DVD to the hard drive and installing dirrectly, I've tried defragmenting my PC, I've tried clean booting my PC before installing, I've scanned the disc files for virises and corruption.  I'm completely out of ideas.  It is very frustrating.
