Why not.
However, pls keep in mind. I'm a Newbie for AUTOIT. I just start to learn it. My first experience was for a Japanese apps which is not producing a setup.iss with Serial & User information, B.H.A B’s Record Gold. And the second experience is this BLACKICE.
Again, my scrip is very X very simple because I do not know well about AUTOIT, but it works. You can install BLACKICE 3.6 cob in silent if you have your own serial.
I hope someone who knows AUTOIT make a much more smart script using my simple script!!

EDIT: This is AP-OFF version for silent install
