I bought a educational CD for my son, contains some PDF file which have useful information and would like to back up. These PDF file are read only and can be read only using the application. Neither I can open them nor copy them in windows explorer/Acrobat/Nuance/Foxit.

I have tried ISO Buster/PDF converter are not successful as the file cannot be read or opened directly.
