    Hi there,

    as far as I know you should be able to download versions for the .Net Framework here: https://dotnet.microsoft.com/en-us/download/dotnet-framework
    I assume that after installing the system may need a restart and you may need to run the install as Admin (right click usually shows the option to Run as Admin (if your account has the rights)

    Hello @Randy Hutchins

    Thank you for reaching out to Microsoft Q&A and informed us about the issue. Based on your report, that message indicate that the Brother software you're trying to run is built for .NET Framework 4.0 but it is not installed on your PC yet, to troubleshoot this, please follow:

    1. Install .NET framework 4.0 directly:

    2. In case installation is blocked by Windows:

    • Right-click the Installer > Properties > Check Unblock (If showing) > Apply > OK
    • Right-click Installer > Run as Administrator

    3. Enable through Windows Feature (If the above step can't solve it):

    • Open Run dialogue (Windows + R) > input optionalfeature.exe > Enter
    • In the list, check .NET Framework 3.5 > OK > Wait for Windows to install
    • Retry the .NET 4.0 installer
