    Hello everyone!
    I tried everything that can be found on the internet, i tried to download from microsoft website, no luck, tried the offline install with the win 10 installer, nothing worked. I really need a fix, so please try to help me!
    <solved> I did the same thing. With no resolve. My computer did some updates few days later. Then I tried activating the Windows feature in Program files and then it worked. It must need a Microsoft update in order to install the framework 3.5... My suggestion would be to simply keep updating then try.

    Note: My windows 10 installation media (1511) didn't have the required 'sources' folder on it. I had to use the media creation tool to build a dvd which had the required folder.
    Then the following command worked for me!
    dism /online /add-package /packagepath:E:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab

    I tried all of the above to no avail. What did work for me was to go to the Windows component option in Control Panel >Programs and Features and check the .Net Framework 3.5 checkbox and the 2 listed under it as well. If I just checked one it didn't work and I got the error code we are all getting. Not sure if this will work for everyone but I have been racking my brain on this and this is the only thing that worked for me.

    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:E:\sources\sxs
    Where the Source:E was the USB I used to do Win10 installation (E: should be whatever your drive letter is with the windows 10 ISO)
    As letter case and spacing is very important, copy & paste the command into Notepad and change the drive letter only, then copy & paste into an admin command prompt.
    This worked for me too, but it's important to note where the "sources" folder is on the USB drive. In my case, the media can install either 32 or 64 bit versions of Windows 10, so I had to add a folder level in my command. In my case, the command (for a 64-bit installation of Windows 10) ended up being:

    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:F:\x64\sources\sxs
