Hey, I've noticed on some other machines that the first time, or first instance of protection being enabled in some other system protection suites, or even installation procedure it's self, can occur differently, and in some instances not occur to the program in questions full intended effect on a sp2 system, over a sp1 system, and visa-versa. But i don't know if this would be the case with pgv.3, so basically in short, when is the best time to install pgv.3 ? Befor you install sp2, or after you've installed sp2. Cheers, Meed.
Meed, It should not make any difference but if you have the choice I would do SP2 first and let it settle in.
