Persistent problem when installing .Net Framework 3.5 in Windows Server 2012

    Question

  • Hello guys,

    I tried installing .Net Framework 3.5 on Windows Server 2012 but none of the installation methods seems to work on me, I referred to the methods such as:

    1. CMD : "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:z:\sources\sxs /LimitAccess"
    2. CMD : "Dism.exe /online /enable-feature /featurename:NetFX3 /All"
    3. Powershell : "Install-WindowsFeature Net-Framework-Core -source Z:\sources\sxs\"
    4. Server Manager : Add Features -> .Net Framework 3.5

    The Windows Server 2012 DVD is on drive Z. I obtained these steps from these references:

    • http://technet.microsoft.com/en-us/library/dn482071.aspx
    • http://msdn.microsoft.com/en-us/library/hh506443.aspx

    I have also modify the group policy setting to enable "Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS)" as instructed in references:

    • http://technet.microsoft.com/en-us/library/dn482067.aspx
    • http://technet.microsoft.com/en-us/library/dn482065.aspx

    However...I keep getting error 0x800f081f. I also referred to the same case happened before to someone else as can be seen in:

    • http://social.msdn.microsoft.com/Forums/en-US/288c7b95-f1b3-4afa-9cab-5d404f7a0f8e/windows-server-2012-cant-install-net-35?forum=netfxsetup

    Nevertheless, my problem is still not solved. Here is the DISM error log newly created with method 1 as mentioned above:

    Any suggestions to solve the 0x800f081f problem? The Windows Update is working normally as I received the updates regularly. I only installed English language on the server. Thanks

    This has worked for me in the past:

    Dism.exe /online /enable-feature /featurename:netfx3 /source:g:\sources\sxs /all

    where g: is the drive letter for the DVD player where the Windows Server media is inserted.

    I've seen this command fail due to corrupt media before, try to download and mount a fresh iso

    Also try to install from the GUI:

  • Many thanks for you Sam, your solution worked flawlessly!

    Apparently, only KB2966827 is installed among from the three of them so I only uninstalled KB2966827, and I downloaded DVD ISO from:

    • http://www.microsoft.com/en-us/evalcenter/evaluate-windows-server-2012

    Then, I add the .Net Framework 3.5 feature via Server Manager as you suggested...and it succeeded. Thank you for your help, really appreciate it.

  • I found that finding the Trustedinstaller.exe and placing it back to System32 or Wow folder elevated to run as administrator under windows Vista worked for me after weeks of issues with 3.5 on my windows 8.1
