Silent install switches for iTunes 10 for Windows

I want to do large scale silent installations of iTunes 10 for Windows.
I also don't want iTunes it to automatically run, once the install has finished.
I'm using the /quiet /passive switches.
The program seems to install without a problem, but when it tries to automatically run it gives an error message.

Apple Application Support was not found.
Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again.

Error 2 (Windows error 2)

I'm not sure how to automatically install Apple Application Support, which would presumably solve the error message problem.
