I upgraded to Windows XP and did not remove NAV 2005 beforehand. I have tried to uninstall and re-install, however while installing I get an error message "this MSI must be launched through setup". I click OK, it then starts to install and after a few minutes, I get another error message " Error 1606. Could not access network location "::\Documents and Settings\All Users\Desktop". Hitting either retry or cancel ultimatley ends up with a failed installation. Any ideas? richie_rich66.....I would have a look at this .....

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? http://service1.symantec.com/SUPPORT/sharedtech.nsf/pfdocs/2003082911090713Merlin_2........I have followed this procedure all the way through un-install and re-install at least 3 times with no success. The fact that when I re-install it only installs 2/3's of the files is where I think my problems lie. I just don't understand why it would only partially install and then POP up the window telling me that install is complete and to re-boot.when you uninstall norton did you go into the reg...and dump norton> and from the C:\Program Files....uninstall program dont all ways work...is this install disk ok...was wondering if its faulty....the webpage mentioned downloading live update re-director?also can you try to load it in safe-mode..richie_rich66.....Have a look here
