I've just inherited an InstallShield 2009 project from a guy who left (oh joy) and am trying to get the setup.exe to run in silent mode. The project is a Basic MSI project and according to the documentation, I should be able to specify the /s switch combined with /v/qn to make the installer and MSI process silent. However, when I do this, the process shows all the dialogs as normal. I've tried generating an answer file with the /r switch, but this fails to produce any sign of a setup.iss any where (I checked the windows folder, which is where it apparently goes).
Why would the process be ignoring the silent commands? I can see nothing in the install log that indicates a problem... The command line I am using is this:
setup.exe /s /v/qn
I've tried various combinations of lower and uppercase to no avail. Any advice would be appreciated.

Edit:
I've also tried:
setup.exe /s /v"/qn"
Which did not work also.
Edit 2:
It might be worth pointing out that the installer is performing and upgrade from a previous version of the product to a newer version. The first dialog that pops up is the "extracting msi" dialog followed by the "welcome to upgrade" dialog.
