Just wanted to mention that I have seen similar issue with an HP Pavilion computer a while back with a different piece of software which was Roxio Easy CD Creator 4.0, in which I had an orphan registry entry cause havoc when trying to install version 5.0. The problem was that the HP image that came with that system and restore discs had orphan registry keys for Roxio version 4.0 when version 4.0 never came with that low end Celeron when bought new. ( I guess HP decided to improperly remove Roxio 4.0 from a different build and make that the system image for this lower end model to have this happen. There is no other likely cause for this orphan key issue. ) I had to fix the flawed registry which was part of the HP system image into order to get my CD-Burner to work with Roxio 5 that came bundled with it.
If you find that Access 2007 is not installed and it still thinks that it is... you can try Karenware Registry Pruner

I was able to find the problem and remove it, then install newer Roxio 5 to my system and be able to burn CD's
