I've got a fresh Windows Server system on which I installed .NET. I have an application whose manual advises me to turn on these Features such as ".NET Extensibility 3.5" etc. but I don't see "Application Development Features" anywhere on my list of Features. Here is what I need:

and here's what I see:

am I looking in the wrong place? I'm told to go to "Internet Information Services > World Wide Web Services > Application Development Features and enable the ASP.NET features" but I can't find it!

    Hi，MichaeIlevin

    I'm told to go to "Internet Information Services > World Wide Web Services > Application Development Features and enable the ASP.NET features" but I can't find it!

    You can't find the folder or you can't find the .net .NET Extensibility 3.5? If the latter, make sure you have installed the .net framework 3.5:

    download .net framework 3.5

    If your questions is you don't know where it lies:

    Open your Control Panel, choose
    ->Programs and Features
    ->Turn Windows features on or off
    ->Internet Information Services
    ->World Wide Web Services
    ->Application Development Features
    ->.NET Extensibility 3.5

    Hope can help you.

    Best Regards,
    Jerry Cai

    Thanks Jerry!!

    I can't find the settings that are shown on the thing I'm trying to check to "on":

    those are the items the manual for the application wants me to check, but I don't see them anywhere.

    I tried to follow your instructions, but for example I don't have "Programs and Features" - the closest I see is "Programs":

    Then I downloaded and tried to run the installer on the link you provided, but I see this:

    what am I doing wrong?
