I have now gotten past this problem with NAV 2005 only to encounter another. When Norton installs, the bar graph indicating how far along the installation is, gets about 2/3 of the way finished and the installation complete window pops up. By clicking 'finish" it then reboots the computer. After running LiveUpdate, I get the error "LU1812 an update failed to install". On the list of programs there is the red X nest to the Symantec Redirector. I followed Symantec's solution all the way through to uninstall and reinstall with no luck including following their recommendations for installing after a failed installation, removing Norton after add/remove does not work, etc. Any ideas?
