enable the feature .Net 3.5 framework via servermanager in windowsserver2012

  • i am trying to enable the feature .Net 3.5 framework via servermanager in windowsserver2012, but its throwing error "the source files could not be found".

    But i placed the dotNetFx35setup.exe in the source file location.

    any suggestions ?

  • use the command line to enable it as follows

    Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccess

  • Your best bet is to redirect the install to the sxs\sources on the instalmedia.

  • Windows 2012 and Windows 2012 R2 require their own source media for the .Net 3 install. Even though Microsoft has very large amount of software currently in support that people might want to install on Windows 2012 that needs .Net 3, getting this installed is not as simple as it should be.

    You need to get a copy of the install media for Windows 2012 (or Windows 2012 R2 if you use that), and direct the DISM command to the \sources\sxs folder on that media. The sxs folder can be copied to your server if you wish and if you do this direct DISM to use your folder.

    Windows 2012 and Windows 2012 R2 use completely different files to install .Net 3, so it is possible to copy the sxs folders from both sets of install media to your own install folder. The 64-bit versions of Windows 8 and Windows 8.1 use the same install files for .Net3 as the server version. The 32-bit versions of Windows 8 / 8.1 need 32-bit files from the Windows 8 / 8.1 sxs folder that do not exist in the Windows 2012 sxs folder. The .Net3 install process seems to reference over 1000 files in the sxs folder, so it is far easier to copy the whole folder than it is to work out which files may be needed.

    Therefore if you create a combined sxs folder containing both 64-bit and 32-bit files you can use the same DISM command regardless of which flavour of Windows 2012 or Windows 8 you install on.
