The program installed quite happily on my old Windows XP Pro computer, and the DVD drive is able to read other installation discs, so it doesn't seem to be a hardware problem.

Any ideas? I am getting desperate!

Could be the disk itself or the drive. A few things to try - try cleaning the disk and running again, try copying the entire disk to a hard drive and installing from there, try copying the disk on another pc.
