Hello Anti-Vera,
Some recent information I received indicates that you should be able to update to NIS 2009 on your new Dell and also add it to your spare laptop.
There are few ways to update to NIS 2009, but a great number of people have been successful installing NIS 2009 right over top of NIS 2008 as the newer Norton Products are designed to do this.
I know you have the key saved in your Norton Account, but you may want to write it down in case it is needed.
1) You can download NIS 2009 here and then choose the "Save" option as opposed to "Run". Save the file to a convenient location that you will remember such as your Desktop or My Documents.
2) Once the file has downloaded, click on the icon and the process will begin. The first stage is that NIS 2008 will be automatically uninstalled. This may take quite some time, so please be patient and do not interrupt the process thinking that it has stopped.
3) During the process you should be prompted for a restart - please do so. Once the uninstall of NIS 2008 is complete, NIS 2009 will then install itself. This will be much quicker than the previous process. Your activation key should automatically be picked up, however if it is not, you will be given the opportunity to enter it. If there is any issue with the key recorded in your Norton Account, you should be able to use the key from the reinstall CD, but I would try the one from your Norton Account first.
4) I generally recommend that once NIS 2009 is installed, you perform a manual "Run Live Update" just to be sure you have the latest definitions. Of course, the product will continue to gather live updates automatically.
Once last "housekeeping" item: After the successful NIS 2009 installation, go to Add-Remove Programs and look for Symantec Live Update and Live Update Notifier. If you are not using any other Norton products which depend upon these, you can safely uninstall them as they are not required for NIS 2009.
When installing on your spare laptop, if the laptop has a recent version of NIS, then follow the above procedure. If it has a different brand, the first step is to be sure any previous security programs are completely removed. If you have any questions about that, feel free to provide us with the name of the previous security software.
The rest of the NIS 2009 installation process will be similar to the above, however you will have to manually enter the same activation key as used above.
If you have any questions, you know where to come!
