Manual Installation using the System's File Browser

The approach is recommended, especially if you update from an older version to a newer one, as all previous addon preferences will be kept.

Keep in Mind

As of MACHIN3tools version 1.8, there is an integrated updater, that allows you to do an update installation from inside Blender, without loosing and previous addon preferences.
