DVD doesn't seem to run exe-files

[union jack38]

its not the auto insert

seems like something on the computer is stopping exe files registering on cd or dvd roms this also includes original discs

i can copy any files from drive ok
but when i try to copy an exe file i get the message
(only part of a read process memory or write process memory request was completed)

also the exe file dont look like they should they just look like a basic exe file with no icon
