My Norton I.S.2011 expires next week and I have been given a new copy of 2011. I thought all I had to do was to uninstal the present programme and install the new copy but this does not seem to work. I used the Norton uninstall tool and restarted the computer. I then put the disk in the drive, got a message to choose install but after that I got a dialog box for Epson appear which I cancelled. After this there was nothing so I went to the disk file contents and ended up installing my previous programme. I was surprised as I was not asked for the product key. Will I have to wait till the programme expires before trying to install the new disk. Perhaps the problem is that it is the same programme although a different disk and Norton want me to renew the existing one which will cost me and as I have got this brand new unused disk I do not want to do that. Any suggestions welcome.
