actually for what it's worth, I belive this has been an issue at least since the last RC2 rls. I posted a couple on the exact same issue.
NT4 SP6 486/66(stfu it's a work pc
) 128mb 2gb
XP Pro AMD K7 396mb, 10&6gb
haven't tried RC3 yet, can't seem to get a good download. They are all saying "corrupt installation file". Probably our great wireless @ 756/256 for $129/month
