HOW TO INSTALL
Simply extract the IFF file and place it in your MLB 2K12 directory.
Your MLB 2K12 directory can be either in:
C:\Program Files\2K Sports\Major League Baseball 2K12

That's all you need to do. If it asks you to overwrite the file, say YES and OVERWRITE.
After that, just start the game up, and enjoy!
