I was purchasing updates to my Norton 2002 so I decided to upgrade to 2005. When starting to install, it told me to remove the old version. I did that with no problem. Then when I started installing the new version (Norton Internet Security 2005) I got this message: “Setup has encountered a problem and needs to close. We are sorry for the inconvenience” I use WinXP Home Edition. I ran all my Ad-Aware and SpyBot programs. Can you help? I don’t like to be without Norton.
