I contacted Sony about the possibility of silently installing their products with the CD pre-filled and they responded by providing me with special site licensed editions of their installers (I do not have the skills to be able to open them up and see exactly how/if they differ from the regular/update installer) along with a .dat file.
This is a copy and paste from the PDF they sent me with the instructions (full link below)
In the Command Prompt window, type the name of the installation utility and add any required
options to configure your installation. For example, to install Movie Studio Platinum, you might type
moviestudiope12.0.755.exe /q /v:XXX-YYYY-ZZZZ-0000,AAAAAAAAA-BBBBBBBBB-CCCCCCCCC-DDDDDDDDD-EEEEEEEEE-FFFFFFFFF /x:setup.dat
