It maybe possible, if it uses a MSI style of installation, you can just edit the MSI to point to the same DVD OR if it comes with installshield or wise installer, then its possible to get the install program and edit the installer ? I've only done the MSI style ones, and also the ones where you can just copy over the files onto the same DVD... I'm pretty sure if you have a "program files" directory on the cd's you can simply copy all the contents into that directory and burn away... But as I said, MSI installers are very easy, and I haven't had much luck with the other installation types. Hope it helps
