I hope you solved your problem by now.
If not, I had the same problem this morning. Deleting directories , stopping the spooler, deleting drivers / directories by hand did NOT help.
An hour ago I got a small tool from the HP Hotline called " Scrubber2.0.zip".
This tool is some kind of magical deinstaller, et voila : the installer routine now worked perfectly. Go figure.
The only thing that went wrong is that the easy management software was deinstalled too... Now I have to go find my CD ...
