While installing or uninstalling Norton Internet Security or Norton Personal Firewall, you see the error message "Instopts.dat is missing" and the installation stops.

Solution:

This error can occur when a registry key for the Norton Internet Security or Norton Personal Firewall uninstaller remains after the rest of the product has been uninstalled. It can also happen if there is a problem with the Microsoft Windows Installer. To fix this problem, start with the first section, "Deleting a registry key," and follow the instructions from there.
