If you want to deploy Quicktime 7.6.5 with SCCM 2007 there are some recomendations..
You need to extract QuickTimeInstaller.exe.
The components are:
Don't try to push QuickTime.msi, there is always an error message in log file.
Create package with QuickTimeInstaller.exe and push it.
But you'll receive message that Quicktime to work need AppleApplicationSupport.
Then create SCCM package and push AppleApplicationSupport.msi.
And Quicktime works... :))
