I have installed Norton Antivirus 2004 on my computer. I had the 2002 version prior to this. I thought I uninstalled 2002, but it is still there. 2004 version is also on the computer. I cannot get Norton to install. I was able to get as far as install and extract, but I then get a message that says "Setup has detected that a previous install or uninstall has been completed but requires a restart. Please restart your computer then launch setup again." I restart the computer and then go back in to launch the program and I keep getting this same message. 2002 is still on the computer at this point. Any suggestions?

Here are the instructions for removing NAV2002 at Symantec:
