Install .net 3.5 and 2 RRS feed

  • Question

  • Hi,

    Is it possible to enabled .Net 3.5 on Windows 2012 Std Edition with Windows 2012 R2 Media. We tried installing it from server manager as well as command prompt by running

    Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

    but got the below error

    Deployment Image Servicing and Management tool
    Version: 6.2.9200.16384
    Image Version: 6.2.9200.16384
    Enabling feature(s)

    The source files could not be found.
    Use the "Source" option to specify the location of the files that are required t
    o restore the feature. For more information on specifying a source location, see

  • Hi,

    There is no stand along .Net Framework 3.5 pack for Windows Server 2012 on Microsoft Official website.

    Also, in general, we can using Add roles and features wizard to enable .Net Framework 3.5 feature. If source files for Windows Server 2012 installation are not on the local computer, we need to specify an alternate source path for installation.

    Please note that, the source media should be same OS version as your server system – it should be Windows Server 2012 (not Windows Server 2012 R2). 

    Detail steps mentioned in “Windows Server 2012 R2: Install .NET Framework 3.5 Feature (Offline/Online)” can be considered as reference:

  • Have you try this ? 

    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs

    Make sure the sources path is correct. In other words make sure the Windows Server DVD or ISO is in the correct Path.  where D:\Sources\SXS is the DVD in your D: drive. Other wise if you have your installation files or SXS files in another Drive Letter just replace the D:\Sources\SXS location with your location Path. 


    Thats your error. 

    More info here.

    Good Luck

  • The easiest method is via Server Manager\Add Roles Features
