Hi! I'm trying to do a silent install of a small application, ProFile 2008.3.1 from Intuit. But I'm having problems with the driver that the installer need to install because it isn't sign. Here's what I have so far.

gpsetup.exe -s -f1"C:\\Temp\setup.iss"

setup.iss:
[InstallShield Silent]
Version=v7.00
File=Response File

And, finally, I overwrite the file Startup.ini with this:
//
// Comments: Use this file to configure an access code for all users which is Useful for Workstation Installs.
// Administrators can modify this startup.ini file, by adding a valid
// Licensee Name and Access Code.
//
// Using the following format, enter your valid Licensee Name and Access Code below.
//
// [License]
//
// Name=John Fakename
// Code=1AA1 AA3A1 AA111
//

[License]

Name=Ask me!!!
Code=1AA1 AA3A1 AA111

All of this works perfeclty except for the part of the installation where it ask to install the printer driver which is not sign. Because of this Windows display a message on the screen, which I don't want, to accept or deny the driver the installation of the driver. So how can I install it myself silently without the need of any user interaction? By the way we are using Windows XP Pro SP3 French 32 bit.
