VHG is right. I recently bought a copy of Norton 360 "Exclusive Gold Edition" from PC World an encountered a slightly different problem. When I installed the disc, I got a "blue screen of death" within minutes of installation and a cyclical rebooting. This happened on two separate evenings.
After hunting around on the Symantec website, I was advised to use the Norton Removal Tool (downloadable online) and install the purchased software from the Symantec website. At the end of the installation, I discovered that my product key had somehow been retained on the PC and the software completed its installation and has worked liked a dream since.
knockavacca as daft as it sounds, PC World would claim that they had no way of knowing that the software purchased was for the Netbook unless of course Luzzly specifically said so.
