Adobe Acrobat Reader Silent & Unattended Install
AdbeRdr940_en_US.exe /sAll /rs /l /msi "/qb-! /norestart ALLUSERS=1 EULA_ACCEPT=YES SUPPRESS_APP_LAUNCH=YES" <br />
This is for version 9.4.0 but should work on all versions of Adobe Reader.
Note that if you are using Adobe Reader X or XI now, there are more up to date versions of doing this using MSI files, all of which I’ve put guides together in more recent posts on this blog.
