DEP on built game

So i made a (early) prototype of a game and built it, everythings ok, then played it, ok, then put it on a flashdrive and tried to play it on another computer. It said something about DEP data execution prevention. and i couldn’t send it over email because it said the filetype was unsafe.

Is the file Corrupted?

or is this a normal thing?

the other computer had vista


DEP is a security feature that can help prevent damage to your computer from viruses and other security threats. DEP can help protect your computer by monitoring programs to make sure they use system memory safely. If a program tries running (also known as executing) code from memory in an incorrect way, DEP closes the program.

Try opening the game in administrator mode.
