Install and update with GPO

Hey,

Is it possible to install and update bricscad on all domain computers with a GPO in Windows Server 2008?
I've read the help but it says it was only working with a response file.

The problem is that I must install bricscad on ca. 100 computers with different hardware configurations.
Now I must boot every pc, log in as administrator and install bircscad. Hopefully there is another way?

Thanks in advance.
