Where do I find my installed product key? I have four WinX computers but my account only shows three.
On the Norton Account web site, are you looking at the My Subscriptions page? On the Norton Account page, click on My Norton, then on My Subscriptions.
Please be sure that Remote Management is turned on. Perhaps then the missing computer will show up in your Account and turn on the Computer. You can edit in the correct names of the computers also. They can be found under Help>About in your Norton program.
