.net framework 3.5 SP1 RRS feed

  • Question

  • I am attempting to install .net framework 3.5 SP1. I continue to get an error message that I need to turn on windows features. I have done this and it doesn't appear that 3.5 is installed. i see where other versions came with the .net 3.0 version, windows vista, but I have windows 7 ultimate and when I download 3.5 to install I got this message. Some of the programs under the tab of 3.5 were not checked so I checked them all and still get the message.\

    Is .net framework 3.5 part of the OS components in windows 7?
    Can i reinstall it 3.5?

  • Hi Hawkstl,

    Welcome to MSDN forums.

    For Windows 7, .NET Framework 3.5 with SP1 is shipped with it as one of OS component.
    For .NET Framework 3.5 with SP1, it includes .NET 2.0 with SP2 and .NET 3.0 with SP2 as prerequisite.
    This means, you have the .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 plus a few post 3.5 SP1 bug fixes on Windows 7. They are OS components. We don't need to manually install it.

    To turn on .NET 3.5 feature, please go to Control Panel -> Programs and Features -> Turn Windows features on or off -> Check the box next to Microsoft .NET Framework 3.5.1.

    Hope this helps! If you have any concern, please feel free to let me know.

    Best regards,
