What do you do if your computer cannot read a game because it says you have a problem with Hpexe?

What game is it? Hp.exe may well be the game's executable file if the game is Harry Potter or some other game that contains the letters HP. If the HP.exe file is on the CD then the CD may be scratched. Try: - Reinstalling the game - Wiping the CD with a cloth to get rid of any dust - Taking it back to the shop for a replacement - Try downloading a replacement HP.exe file from the internet
