it will automatically crack if you click on the "Copy contents of CODEX directory to installdir" in the installer or explore the ISO go to the codex folder and copy the contents manually Game Works Great! XD
It should have its own folder in the IGG-Everybody’s Gone to the Rapture folder, then bring that over to the main one, but if there is no crack or no igg folder then there might be something wrong with the upload, I'm downloading right now so when it is done ill figure it out and get back to you
