Cannot Install Net Framework 3.5 on Windows Server 2016 Standard RTM error 0x800F081F RRS feed

  • Question

  • Hi Guys,

    I'm trying to install Net Framework 3.5 on Windows Server 2016 Standard, but I'm getting the error 0x800F081F.

    I tried the following methods without success:

    1. dism /online /enable-feature /featurename:netfx3 /all /limitaccess /source:<drive>:\sources\sxs
    2. dism /online /enable-feature /featurename:netfx3 /all
    3. Enable-WindowsFeature -Name Net-Framework-Core -Source <drive>:\sources\sxs
    4. Directly in server manager configuring the option for altenate source.
    5. Double click on the CAB file "microsoft-windows-netfx3-ondemand-package" inside sources\sxs.

    Note: I tried with a lot of official ISO of Windows Server 2016, still not working.

    KB2966828, 2966827 not installed.

    Finally I noticed that in the media only exists a CAB package that is "microsoft-windows-netfx3-ondemand-package".

    I hope you can help me Guys, Thanks.

  • Hi, I had the same problem on Windows Server 2016 Essentials and managed to solve it.

    I did not have access to my Windows Server 2016 Essentials installation media, but searching Google for "microsoft-windows-netfx3-ondemand-package" led me to a direct link to the .cab file.

    Pointing the wizard to the .cab file solved my issue and let me install the Net Framework 3.5 features I needed.

    Hoping this helps someone.

  • Is this server using a wsus server? Try setting Windows to get optional features from Microsoft.

    To configure Group Policy for Feature on Demand

    1. Open the group policy editor. For example, on a computer that is running Windows 8.1, from the start screen, type Edit Group Policy, and then select Edit Group Policy to open the Group Policy Editor.

    2. Click Computer Configuration, click Administrative Templates, click System, and then double-click the Specify settings for optional component installation and component repair setting.

    3. Select the settings that you want to use for Features on Demand.

    The settings to try; Enabled and 'Download repair content and optional features directly from Windows Update instead of Windows Server Update Service (WSUS)'

  • Hi,

    There should be a cab file "microsoft-windows-netfx3-ondemand-package" at “\sources\sxs”.

    Please try to install .Net Framework 3.5 on Windows Server 2016 using installation mediam:
    1. Open Server Manager – Dashboard - Add roles and features – Features – select .Net Framework 3.5.
    2. On the Confirmation page click the Specify an alternative source path. Then type the path of Windows server 2016 image, such as “<drive number>:\sources\sxs”.

    Best Regards,
    Eve Wang
