Software Deployment

Hi everybody! I'm new to this website (even though I've been a packager over a year!) but the time of desperation has come to me [:(]

I'm trying to do a silent install of Websense Client 7.6. It's basically and a setup.exe wich gets some configuration settings from a HSW file and then calls an MSI. No matter what I've tried, the install always display the UI, despite the fact that the setup.exe is supposed to include /S and /V switches (if you type "setup.exe ?" on cmd, it tells you that to do a silent install you should use /S/v/qn, but unfortunately it only hides the executable part of the UI, the msi UI is still there, including the license agreement)

Here's what I've tried:
- Creating a transform that adds LIMITUI=1; ARPNOMODIFY=1 and AGREETOLICENSE=Yes
- Adding quotes to all the msiexec commands (like setup.exe /S /V"TRANSFORMS=TransformPathAndName /qn")
- Capturing the response file when creating the transform

None of the above has given me any result, that darned UI keeps showing.

Since that *.hsw contains some configuration specific for the client, I must use the setup.exe to get those settings into the configuration, so trying to use the msi alone will not do the trick. Also, since this software is supposed to be an internet use monitor and filter, it should ask for a password on unninstall, so repackaging it does not sound like a good idea (I believe it could strip the package from the uninstall intelligence, but if I'm wrong, please correct me.)

Any idea will be greately appreciated, and if you ever come to Mexico city, I can offer in exchange an awsome beer and some delicious (and fat-filled) meal [;)]
