Mr. op het Veld,
Can you copy from the CD-ROM drive? Maybe a quick work around is to copy the CD-ROM to a temp folder on the controller and install it from there. Second workaround would be sharing a CD-ROM drive of another PC in your network (if the controller is connected to a network) and run the setup from there. You could also copy the disk on to the harddisk of the PC and share the folder where the installer is located.
About the CD-ROM drive: Did you try other CD-ROMs? Do they also not work. It could be a problem with the CD-ROM itself. What kind of controller do you have and which OS?
Hope this helps,
Best Regards,
