Legacy Builds
    The current build of QuickLicense, AppProtect or DocProtect on macOS requires 10.10 or later. A protected application generated by these tools has the same runtime requirements.

    Excel Software includes Legacy builds of QuickLicenseRT, AddLicense, AppProtect and DocProtect with current versions of these products. The Legacy builds support older 10.6, 10.7, 10.8 or 10.9 computers.

    If your protected application uses the QuickLicense API with QuickLicenseRT, simply drop in the legacy version of QuickLicenseRT. If your application is built with AddLicense, AppProtect or DocProtect, click Build with the Legacy edition to support older Mac computers.
