Hey Ryan or whomever,
A machine I use for G3 the most is at work behind a corp firewall that won't allow me to update via the web... and we don't have modem lines inside.
It's a PITA as without a downloadable update the only way to do it is for me to haul my machine home & use my DSL.
Seems...
I've successfully installed #3 on a three different XP machines. One went flawlessly, the other required closure of all processes running under my username. It seems #3 is sensitive to anything that's running. It then installed fine.
