Got an error while installing Norton Internet Security 2009

Hi,
I was installing Norton Internet Security 2009 on my new laptop with Win 7.
The installation didn’t finish and I got this error message stating that NIS product required Windows XP or Windows Vista.
Did this mean that NIS 2009 I had wasn’t ready for Win 7?
What should I do next?
Please help.

Norton Internet Security
This product requires Windows XP or Windows Vista. Setup will exit.
