Problem:
The Device you have has no DVD drive but you have a CD / DVD for your Software.
Cause:
A lot of developers are moving to a digital download over a physical media as we progress into an ever increasing digital age. A fair few manufacturers may produce systems without a DVD or CD drive.
Solution:
Put the disk into a device that has a CD / DVD drive and copy the files to a memory stick.
Alternatively:
Visit the Developer website and check their Downloads section. This can often be found on their support area.
