.exe within .msi - woes

[Symbiot]

Hi

I have an MSI which will install with /qn.. no worries...

but at the end of the install it spawns a .exe setup to install some drivers...

really annoying...

I've successfully extracted the drivers from the msi and created an install script to add driver certificate to client device and install the drivers.. but now I need to kill the driver install or somehow tell it to install quietly (it'll just say the drivers are already installed when I install the seperately)..

But I cannot find the right way of doing it.. I've had the msi open in ORCA, InstIT, msi studio Tuner, advanced installer and what not...

But I haven't found the place to disable the .exe launch..

Any help will be appreciated..
