After downloading and extracting mmonit-3.7.1-linux-x64.tar.gz, the resulting directory is placed at /opt/. Two files have to be patched:

• mmonit daemon at version 3.7.2 for the x64 platform has to be patched and is placed by default at /opt/mmonit/bin/mmonit
• libzild some library that is placed by default at /opt/mmonit/lib/libzild.so.0.0.0

Instructions on how to patch the necessary files as described in the tutorial can be found on the cracks tutorial page.
