how to do unatteded installation

[MaBuSE]

Hello,
we have to install a lot of "Delphi 2007 for Win32". CodeGear (Borland) uses InstallAware.

My Question: How to do a unattended installation?

If I run "setup.exe /qn" it does something, but after a while an error dialog pops up. "invalid serialnumber" and the install aborts.

How can i provide the serialnumer to the setup.

I want to do an "full installation" but -I want to change the destination directory to D:\\Pro...

We don't need to do a online registration, we have a borland license server.

What must I do?

Can anybody help me?

Thank you

ps: sorry for my bad english, I'm native german speaker.
