Download the quicktimeinstaller.exe from quicktimes site and extract the file into a folder using 7zip or winrar.

Inside the extracted folder create a file called quicktime.cmd and drop these to lines into the file

msiexec /i %~dp0quicktime.msi ALLUSERS=1 REGSRCH_INSTALL_ASU=0 DESKTOP_SHORTCUTS=1 ProductLanguage=1033 /qn
msiexec /i %~dp0appleapplicationsupport.msi ALLUSERS=1 REGSRCH_INSTALL_ASU=0 DESKTOP_SHORTCUTS=1 ProductLanguage=1033 /qn

then deploy the quicktime.cmd as hidden(just so the users do not see the command box)

Had to deploy WinDVD to a collections of computers this silent string worked the best any other variation just caused problems not during local install but during deployment across the network.
