Microsoft provides an uniform way of silent customizing Office products’ installations: OCT (Office Customization Tool).
In order to start it, run the setup executable of the office installation you want to start (32 or 64-bit) with /admin parameter. (setup.exe /admin)
This will start a wizard where you can configure many options, from feature selection, to the smallest details one can imagine.
Once you’re done with the configuration, save the changes. This will create an MSP file that you can use for the silent installation.
In order to install it, run the following command line:
setup.exe /adminfile <pathToMsp>
However, there’s also the possibility of using a configuration xml file for the silent installation, based on the template config.xml that can be found in the core_product_folder_name.WW folder.
Also, an XML file can be created for a silent uninstall.
OCT is available for Office (2007 or later) but other related software such as Microsoft Lync, Visio, Project, OneNote etc.
