This script will install alcohol 120% and dispatch the scsi driver request box. Set WshShell = WScript.CreateObject("WScript.Shell") WshShell.Run ("%systemdrive%\INSTALL\CD\A120\setup.msi /qn REBOOT=REALLYSUPPRESS") WScript.Sleep 12000 WshShell.SendKeys "{TAB}" WScript.Sleep 1000 WshShell.SendKeys "{ENTER}" WScript.Sleep 9000 WshShell.SendKeys "{ENTER}" WScript.Quit copy this into notepad and save it as A120.vbs Change the items after %systemdrive%\install to reflect the location of your copy of alcohol 120%. Call the script from your install.bat or RunOnceEx and it'll automatically click next then finish when that pesky scsi driver thing appears. on slower computers you may need to increase the 9000 to a higher value, and the same with the 12000. It works by calling the alcohol 120% installer with the silent switch, then waits 12 seconds for it to finish installing and the scsi driver dialogue to appear, presses tab to highlight the next key, then enter to push it, waits 9 seconds for the driver to install, and presses enter again to click finish and dismiss the box.
