In other words: are separate operating systems considered separate 'computers' to Webroot?
Best answer by mdrmusic
a) purchase a further 2 opearting system licenses for my existing license key;
b) purchase a separate 3 operating system license key.
So unfortunately there's no current option for a 6 OS license key, but LUCKILY there is currently a 50% off special for WRComplete 1 year 3 operating system license key through the US site and I chose to do that since it was $20 AUS cheaper to take up that option and then add the 2nd license key to my existing account.
Just want to say thanks for all your help here :) really appreciated!
