    Hi @Arne Garvander ,
    .NET December 2021 Updates – 6.0.1, 5.0.13 and 3.1.22
    Refer to the response of this blog, you can manually download and install the .net6.0.1 update.
    Here is the download link.
    https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-6.0.101-windows-x64-installer

    If you want to uninstall .net, refer to this document.

    Best Regards.

    For me, the update was installed as part of Visual Studio 2022 version 17.0.3. Once VS was updated, Windows Update no longer showed the .NET 6.0.1 update as needed.
    If you don't have VS 2022, you might try downloading the update from here: https://dotnet.microsoft.com/download/dotnet/6.0

    Do you mean "install?" I see the same install error you have. I am on Windows 11.

    The .net 6.0.1 does not install with windows update.
    Can I uninstall .net 6.0 instead?
