knightstorm I completely agree with you. Its as if Symantec has designed SEP for a world with 32 bit XP machines. We are a small business (less than 150 employees) and we use 64bit XP and already have begun playing with 64bit Windows 7. So I would have to think many larger companies are moving in that direction. Why isn't there more complaining about this? On 64bit machines Internet Email Protection does not work, nor does Proactive Threat Protection, nor does Application and Device Control, you can't right-click on an individual file and select "Scan for virus", system lockdown does not work, parts of Tamper Protection do not work, and the list goes on (see kb document #2007022310384648).
I have told all my 64bit Vista users that they will be the first ones infected LOL. Seriously though this is a huge concern and I hope someone at Symantec responds to this.
