Hello all. Avant is one of my favorite broswers also. I was a little dissappointed not to find a switch for a silent install. But as KonuS posted, using the vbs script is kinda nice. I had to alter it a little to fit my ver. but it work at least for me when I was testing it on my box. I tried it once on my very first install but I had an typing error.

. Anyways heres the one I edited from his to get mine to work.
---------------------------------Begin Code--------------------------------------------
Set WshShell = WScript.CreateObject("WScript.Shell")
'To Simulate Keystrokes
WshShell.Run app & "avant.exe"
WScript.Sleep 2500
WshShell.SendKeys "{ENTER}"
WScript.Sleep 500
WshShell.SendKeys "{ENTER}"
WScript.Sleep 500
WshShell.SendKeys "{ENTER}"
WScript.Sleep 500
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WScript.Sleep 500
WshShell.SendKeys " "
WScript.Sleep 2000
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WScript.Sleep 2500
WshShell.SendKeys "{ENTER}"
WScript.Sleep 2500
WshShell.SendKeys "{ENTER}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys " "
WScript.Sleep 2500
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{ENTER}"
WScript.Quit

Just copy and paste that in notepad and save it as "Avant.vbs".
BTW, I love this site. All the guides are right on the money. I got my CD ready in a matter hours really. And it ran ran almost flawlessy Runoncex and all.(If it wasnt for my bad typing, I think it wouldve been).
