Installing .NET 3.5 on Windows 8

We needed .NET 3.5 in order to install Windows Live components (though Mesh refuses to install).

12-03-07 Win8 - 3 DotNET fails to download

We went in to add a new Windows Feature and hit the above error.

Windows Features

Windows couldn't complete the requested changes.

Windows couldn’t connect to the Internet to download necessary files. Make sure you are connected to the Internet, and press “Retry” to try again.

Error code: 0x800F0906

A search for “Windows 8 0x800F0906” turned up:

So, we did the following:

  1. Open Windows Explorer
  2. Mount the Windows 8 client ISO by right clicking on it.
  3. type CMD and CTRL+SHFT+ENTER to get to an elevated command prompt from Metro.
  4. dism /online /Enable-Feature /FeatureName:NetFX3 /All /Source:H:\Sources\SxS /LimitAccess

Once complete we ejected the Windows 8 client ISO and were able to move on to installing Windows Live components.

Error: 0x800f081f

The source files could not be found.
Use the /source option to specify the location of the files that are required to
restore the feature. The file location should be either the root directory of a
mounted image or a component store that has the Windows Side-by-Side directory
as an immediate subfolder.
