It's so easy it's hard. In the seperate program files, like VSO, MPF, etc, the setup.exe in that folder will install silently and without prompts, so you need to call the setup.exe for each component (SpamKiller, VirusScan, Personal Firewall, Privacy) seperately. I haven't tested them all yet, but I'll try it tomorrow and let you know if it works. I think it should though.
