Installed but had to manually install previous version of Norton 360 V5 before I could install, after that I found out that my DVD drive no longer worked.
This could just be a coincidence and that the two things are not linked but after installing the Beta version of Norton it flagged this problem up when I ran a diagnostic report from within Norton. The drive was working correctly just 2 days before the download and install of the Beta.
But to get DVD drive to be recognised by PC and with the help of people in the helproom managed to get it back by altering registry.
As I said the 2 things may not be connected.
Windows 7 64 bit.
