I give up trying to do the update,using window 7 and tried installing 7- zip file and still no go,question for those who have not done install,besides light not staying as selected does everything else have to be reset as well after a battery change? By that I mean wattage selected? Battery percentage instead of puff counter? I can live with it staying on 20 seconds instead of 10, hell vct inbox stays on for 1 minute ( ya I timed it) thanks guys
