Auto-answer questions for a GUI install program?

During the install process, we are trying to install a third-party program along with our 'main' program that we install. This third party application is very important (and can't be skipped).

The problem comes in here: the third-party program asks MANY questions when installing on Windows 7, and the user needs to know which are the 'correct' answers. We've contacted the vendor and have never gotten a response (yes! We'll pay!). We don't think a manual will help (who reads that?). And, it's against our licensing to repackage their application into our Installer.

Theirs is a custom installer app, so nothing you've heard of - not INNO Setu开发者_如何转开发p or Installshield.

It's too late in the project to change vendors for this app, so what are my options? Is there a program that we can run that will 'auto-answer' the questions this installer asks?

Sounds like something sikuli might be able to solve. But regardless of your solution, you'll still have to distribute the program answering the installer along with the installer. Or you can package them all up in another installer.
