I am assuming you are referring to a Windows installation of RE5. If so, that isn't a file that is missing, it's a folder which contains texture data for the game models. The only way to fix this is to reinstall the entire game.
just playing the game and crashes saying the em 32 is missing
I understand what you are saying. I am saying that you need to reinstall the game on your PC. If you don't know how to do it, have a parent or someone who understands reinstall it for you.
