You don't have to include any of the files which diskspan_gui creates after you compressed your game. The BIN files includes the game files, the Setup.dll file includes files which are required to unpack the BIN files, and the Records.ini file is required aswell. You just need these files next to compiled Setup.exe installer. César already told you what scripts you could use. There are plenty other scripts you could use. Most of them you can simply compile with inno setup v6+ (unicode version), for some others you need inno setup enhanced version.
