I'm using ESS RC1 on XPx64 SP2. Updating is better in RC1 than it was in the previous trial version. When I hover over the icon to check the version it's always for the previous day. So I log into the admin acct open the gui and under the update header there is red lettering that shows the definitions could not be updated. I have to update manually so I can switch users again to finish what I was doing. The thing is; my pc runs 24/7, NOD32 can update itself if I do not log on for days at a time. That's why I expect ESS to be able to do the same if there is always access to the internet. Thanks ESET, Keep polishing and it will be a diamond.
