    Cannot install .NET Framework 3.5. I HAVE TRIED EVERYTHING


    I need to install the .Net framework 3.5 sp1 on Windows 8.1 for Autodesk 3ds Max for work. I initially noticed this in the Max installer...just quit installing and says I need to connect to the internet. Of course I am connected just fine. Tried Windows update, gave me this error:
    0x800F0906

    Went to the microsoft site for that error, and nothing helped.

    Tried enabling .net 3.5 from the features menu, but got the same Windows Update "connect to the internet" error.

    I tried using command prompt to do this command: Dism /online /enable-feature /featurename:NetFx3 /All /Source:E:\sources\sxs /LimitAccess

    That did not work, even with the installation media inserted, CMD gave me error 0x800f081f saying it could not locate the files on the Windows 8 installation disc (YES I DID INSERT THE CORRECT DRIVE LETTER)

    I even copied the sxs folder directly to my C directory, directed the command to the folder itself and it still gave me the same error. The only thing I can think of to actually make that command work is if I had a Windows 8.1 disc instead of 8.

    I've tried downloading multiple "offline" installers for it, but they all do the Windows Update crap that got me into this in the first place.

    I hope someone can help because I have tried literally everything I have been able to find online and my computer just refuses to install this .net framework.

    Thanks, everyone

    OPEN CMD.exe as administrator
    mount of put your windows dvd in your PC
    past that at the command prompt screen
    " Dism /online /Enable-feature /featurename:NetFx3 /source:\Sources\sxs "
    where "D" is the path letter for the DVD
    then enter
    it will activate net framework on your device

    Thanks for the reply, but the description says that I have tried that already.

    Turn off auto updating from WSUS


    I struggled with this too and got tired of people saying to to just redirect the x:\sources\sxs folder.
    All I had to do, was to make sure the machine is not being controlled by a Group policy for Windows updates.
    As soon as I got rid of that, I was able to get .net 3.5 installed.
    I know this is an older post, but if it helps one person, they will thank me!
