Silent, Passive Installation

Hi I am trying to do a silent passive install on a Windows 7 32 bit machine. So far the command line I have got is as follows:

msiexec /i Libreoffice_4.0.4_Win_x86.msi UI_LANGS=en_NZ Reboot=No REGISTER_ALL_MSO_TYPES=1 INSTALLLOCATION=“C:\Program Files\Libre Office”

This works to a point but it is not passive as I still need to interact with the computer during the install. Can anyone see what I need to add?

Please take a look to this thread:
