Norton 360 version 5 install problem

I have used Norton 360 for some time.  When time for renewal I purchased the Norton 360 version 5 update for 3 computers.

I had problems installing to my desktop and laptop.   After installing Norton 360 I was able to successfully installed 360 version 5 on my desktop.  I tried again to install Norton 360 version 5 to my laptop and I received an error message that the computer's operating system is not compatible.  I deleted the Norton 360 thinking it maybe the problem on my laptop as well.  However, I still receive the same error message when I attempt to install on my laptop.   The Norton 360 was successful last year but now I have deleted it.  What do I need to successfully install the version 5 on my laptop.  Or should I get a refund and purchase another Norton product?
