Could you please post that number to AVG. I'm wrestling with the same problem just not with AutoIt. I have been able to get the script to work on a computer without AVG 7.5 currently on it, but when I attempt a scripted install of AVG 8.0 AV Network Edition on a system with AVG 7.5 currently installed, it fubars . They haven't replied to my emails and I'm on a deadline. Thanks Sincerely, Joshua D. A tired school system tech admin
