What is a binary patch? An binary patch is a newer version of the MuLab binary application file. On MacOS that's MuLab.app, on Windows that's MuLab.exe + MuLab.ID. Installing the latest binary application files quickly updates your MuLab App installation to the most recent version while preserving all your user settings.   Condition Only apply this app patch when you already have installed the full MuLab 9.0.28 package or later, otherwise important resource files may be missing or out of date. In case you do not have installed that full package, you can download it here.   How To Apply It?
