Hello again Bobby,
Thanks one more time for all of your efforts to help me out. My webcam finally got installed without an error message after ten attempts and I thought I'd try installing the HP Deskjet printer for the umpteenth time from my CD installation disk. This time it installed after I proceeded to ignore the Windows warnings that the drivers were not didgitally signed or approved by Microsoft. The bottom line is that the printer works just fine but the scanner dooesn't. Will be in touch with HP later this evening.
