I've been trying to do the same thing. For the previous version I was using an AutoIt script that was simply wait for the window and hit Enter, but that did not work with this new version.
Discovered today though: Empty all your %TEMP% directories. Run the setup programme like normal, but let it get to the point where you are about to click Next. Do not pass it any switches. Now go into all your %TEMP% directories and find an MSI. Mine was named dfc61.msi. Now you may execute like this:
msiexec /i dfc61.msi /qb. The problem is the licensing. The licensing application for Ad-Aware will run immediately after the installation is complete, and what I found was that AutoIt cannot identify any elements of this windows, so only click/mouse functions could possibly skip this part. However, if you kill this programme, AAWLic.exe, then Ad-Aware on first run assumes you clicked 'Use Free'.
You will need to use AutoIt a little bit. First, copy the MSI to %SYSTEMROOT%\system32 because that is where msiexec is, unless you want to code in a batch file a way to give the full-path to the MSI to msiexec. In my case, I'm running it like the following (AutoIt code): Run("msiexec /i dfc61.msi /qb"). AutoIt does not tell msiexec that it's running in somewhere else other than system32 and then is able to change the reference of the MSI file. If the MSI file is always at one point, you can change it in the AutoIt code. Essentially, you need to run this part, then wait for the window of the licensing which is handled by AAWLic.exe, give it Alt+F4 to kill it. Updater now runs, but it will automatically close. Then continue as normal.
CODE
@ECHO OFF
REM Copy MSI file to system32 temporarily
copy /y "dfc61.msi" "%SYTEMROOT%\system32\dfc61.msi"
REM AutoIt executable
"ad-aware-free-installer.exe"
REM Now remove the MSI file
del "%SYTEMROOT%\system32\dfc61.msi"
exit
You can do more of course, but the main thing is getting past that license screen. Here is the AutoIt code:
CODE
Run("msiexec /i ad-aware-2008-7.1.0.8.msi /qb")
WinWaitActive("Product registration")
; Send the Alt+F4 combination
Send("!{F4}")
; Updater now runs, but it closes automatically
I usually remove the desktop shortcuts, and the shortcut to Ad-Watch since it does nothing.
CODE
del "%USERPROFILE%\Desktop\Ad-Aware.lnk"
del "%USERPROFILE%\Desktop\Ad-Watch.lnk"
del "%USERPROFILE%\Start Menu\Programs\Lavasoft\Ad-Aware\Ad-Watch.lnk"
Hope this helps. I've tested this several times on a VM, seems to work pretty good. Yes, the updater sucks in that it has a time out of 10 seconds to wait, but this is negligible to me. I will have this tested on a real machine by tomorrow for sure.
