If you install new Nvidia drivers and get a error during the install it might be the Zone Alarm firewall software. I don't understand why the firewall software would cause a problem with installing graphic drivers but it does.
It's because you're allowing the installer to install Nvidia snoop on me, aka Nvidia update. ZoneAlarm is going to attempt to block any software that's hitting the net unknown/without implicit ok.
you're title is miss leading, it should read windows and Zone Alarm Firewall Dont Mix Just pause zonealarm whilst installing. It is strange as i use lookNstop firewall and nvidia Never calls out when installing.
