if you check the helpfile, see the add from database section, that will explain it Ok, got that. But that falls short of an explanation like this for Adobe Acrobat: 1. Start the original Acrobat 6.0.1 setup. 2. It will de-compress itself from the FEAD optimizer 3. Look in "C:\Windows\Cache" for the installer with MSI. 4. Open a command-window into that folder, and run the main MSI with the "/A" switch to make an admin-install point folder. 5. Copy away that folder safely, and install from there. 6. Download the 6.0.2 update, and start the setup, but don't click "Next". 7. Look in the folder "C:\Documents and Settings\UserName\Local Settings\Temp\_is---" to get the extracted update. 8. Now keep both the admin-install and the update in one folder. 9. SFX them to extract silently to a folder of your choice. 10.Have your unattended scripts run both (the main+update) the MSIs with the /QB switch. The total time-saved during uA setup = 2 mins. Space saved on CD = 10 MB. In time the database can be a fantastic resource all by itself. Having all kinds of information for different ways of setting up the different programs. In any case, that was just an RFE for the future
