Limitations of CPT on CD/DVD formats

Older products delivered on CD/DVD have certain limitations.

The National Geographic Learning Classroom Presentation Tool (CPT) is delivered on USB drive, a small external hard drive sometimes referred to as flash drive.

Before the availability of USB technology, CD/DVD was the standard delivery method. Some of our older products remain in this CD/DVD format.

Due to advances in hardware and operating system technology, we are finding certain limitations associated with these older CD/DVD CPTs.

The most frequent limitations encountered are:

  • The CPT requires a disk drive and you do not own one
  • The CPT does not install
  • The CPT installs but does not run

If you experience one of the above mentioned limitations, please contact your local Sales or Marketing representative to learn about the availability of new editions or alternative options.
