that can be installed on any three of your choice PCs and since the one computer is "dead" and being replaced it is only going to be used on the threee functioning computers so such use is legal by the Norton EULA.
if there is any problem during the installation (there shouldn't be) on the new computer simply call Symantec Support or Customer Service and explain why it is installed on a different computer and they will be happy to assist.
I have Norton Internet Security 2009 (3 license version) installed on 3 pcs. One of these has recently 'died', and I have purchased a new laptop to replace it. I am currently running a pre-installed 30 day trial firewall but would like to install the Norton software (I have the disk). Will it install OK and work properly even though it will, in effect, be installed on 4 pcs?
Thanks in advance for any help.
