I need a way of finding a silent install switch for the software that came with our Epson ELPDC06 visualisers. The software is something from arcsoft which isn't too bad once it is installed but I have no intention of going around to all staff member and installing this manually when I'd much rather make a silent install script or msi wrapper.

Anybody have any ideas when /? gives nothing /s runs but terminates before install. I can't extract it even though it tells me it's an installshield installer.

I think I shall be pulling my hair out over this one unless I can get some help
