Thank you to all who replied. I am in the process of trying to engineer this update. I cannot decided whether to use McAfee's uninstall program (which removes other program files, doesn't complete the uninstall, and leaves old McAfee folders) or write a kix script to totally remove all files, processes, and registry entries. This may be my best bet seeing that I can control what is removed. I also may end up having the new McAfee 4.5.1 install remove the older versions (4.0.2 & 4.0.3). If I go this route, then user intervention will be required. Unfortunately, McAfee VirusScan 4.5.1 requires 2 dialogued reboots; one for the installation of Microsoft's Windows Installer, and one final reboot.

Thanks again, Blake - God Bless America
