Thanks so much for all of your help Bobby. I followed your instructions to the letter and was able to get the printer operational but only by allowing the installation of a non authorized driver which as the warning lets you know in advance is unstable. To make a long story short, it won't allow the scanner to work or for the HP Solutions package to be recognized. The printer is a Hewlett Packard All In One F 4140. I might point out that a Hewlett Packard technician worked online with me in control of my computer for five hours on Thursday night and another three hours the next evening. He was unable to install it either from the HP website or from my CD rom. I'm convinced that there's nothing wrong with the unit and that the problem lies squarely in my computer. Sure wish I had the answer. I might check with Microsoft tomorrow if I can't figure it ot.
