I tried to install Live Essentials 2012 on Windows 8 and it required .NET 3.5.  I tried to install it (both download and from Programs and Features) and the installer tried to download the code.  The download would fail with a 0x800F0906 error:

Windows couldn’t connect to the Internet to download necessary files. Make sure that you’re connected to the Internet, and click Retry to try again.

Some googling ensued and I found a fix.  Pop in the installation media for Windows 8 and run DISM from an elevated (admin) command prompt.  E: was the path to my Windows 8 installation USB.

Not exactly user friendly!  The Live Essentials 2012 install worked fine after that.

It appears that this is caused by the machine being policy configured to use WSUS or similar with the download of .NET 3.5 not being available.

  1. There is a new GPO to address this exact problem
    “Specify settings for optional component installation and component repair”
    Located @ Computer Policy -> Computer Configuration -> Administrative Templates -> System
    This GPO can enable Windows to use Windows Update to download missing installation files. By default, (if you don’t change this GPO) Windows will try to look for missing files in location where it was installed from, usually DVD; this is hardly a convenient default

  2. There’s also a couple of reg keys which you can apparently add which will get around the WSUS issue without fiddling with Group Policy – useful for scripting. That said, the keys don’t appear to be working for me. I am trying to install .NET 3.5 via a script and without any local source media to pull the SXS stuff from. I’m having zero luck – the DISM operation fails and the log file shows “Encountered an unknown option ‘featurename’ with value ‘NetFX3′”

  3. First i wanted to use the Group Policy settings on our SBS 2011 to enable this setting, but i assume this being Win8, it’s not included (yet).
    So than i tried to change the local policy, but for some reason that didn’t work either (i admit i didn’t waste too much time with it).

    Ended up using Aidan’s procedure, that worked fine.
    Thanx

  4. this didn;t work for me…… :-(
    it is saying that the feature or feature name you are trying to on/off is unknown!! any suggestion?

  5. Having this same issue on a Surface Pro, no CD drive or installation media.
