Thanks for your report. This error indicates that part of the graphics library code used by the installer has been corrupted, at which point it cannot really hope to give a sensible error message. This error is normally due to a faulty CD/DVD disk or drive. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, or to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers).
