Re: I can't install Norton Antivirus 2009 with existing Intern Sec. 2008

I done this in the past, but this year,   I am getting an error message when i try to intall NAV 2009  with  existing  NIS 2008 on computer (XP Media Center ed. OS).

It says I have to uninstall  NIS.    I don't want to loose the extra features..  

is there a way to use this CD for the virus renewal subscription without uninstalling NIS 2008?
