Internet Security 2011

I am trying to install Internet Security 2011, but when I click on install it comes up with a screen saying "select your uninstall options" for 2011.  If I click on this it comes up with why are you leaving Norton.  I have never had this problem before. I already have Norton 2010 which is due to expire and I am running XP.  Please any suggestions.

 

Thanks

Alan
