Joel, HP scanners are very difficult to get going, but great once going. I have a 5100C that takes several installs to get to work, meaning that several reboots seem to be the trick. Usually 3 or 4. Have not pinned down the optimum method, but I usually unplug everything and install the software, connect hardware and reboot. Uninstall/install reboot. Reboot. Reboot. Somewhere inbetween or perhaps the next day, it decides to recognize the hardware. Now I have cloned my o/s and that install works everytime. Perhaps a registry backup from when it was working may work for you. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com The NOSPIN Group provides a monthly newsletter with great tips, information and ideas: NOSPIN-L, The NOSPIN Magazine Visit our web site to signup: http://freepctech.com
