Hello Michael,
Just to confirm what my colleagues from GRAITEC UK told you directly:
To be able to install the software you need to download the ISO Image and then burn this image to DVD.
Just some information regarding an ISO image.
What is an ISO image?
An ISO is a file that contains the complete image of a disc, from sector 0 to the end.
Such files are often used when transferring CD/DVD images over the Internet, and are commonly used as a way of offering Linux distributions for download.
The latest versions of CentOS, for example, are available from centos.org as ISO images.
Once you have an ISO image on your hard drive, you can burn it onto a CD or DVD using one of many ISO-burning software packages.
Important notes:
To create a bootable CD or DVD from an ISO image, you must burn the actual ISO image onto the CD / DVD, not just copy the ISO file to the CD / DVD.
For software not covered below, look for a Burn Image option to accomplish this.
Warning: Just copying the ISO file to the CD / DVD will not produce a usable disc.
Take care to download ISO images in binary mode if using FTP. By default, Netscape downloads the file in ASCII mode, which corrupts the image.
Do not operate any other programs while the CD / DVD is being written to.
Do not bump or nudge the CD / DVD burner while it is operating. Vibrations can cause the burning process to fail.
If you don't have a CD /DVD burner, find a Linux user group near you. Someone will be sure to help.
If you would rather purchase pre-made CentOS CD / DVDs, please see our Official CentOS CD / DVD Vendors
