    Hi,

    I know this might sound dumb, but what has to be on the stick or drive in order to install it? I'm not good with computers and English is not my native language.
    Sorry for the dumb question.

    The same Windows 10 ISO as your Installation.
    For example, my current Win10 Version is 14393.693(click Windows icon and type winver)
    Click image for larger version.

    To get the ISO go here: Download Windows 10
    Use the tool to either get the ISO file, or create USB or DVD installation media.
    To run the command, the ISO file mounted in File Explorer is enough, but a USB is always a good idea to have on hand, for "emergencies".

    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.
    Woo hoo! Worked nicely in 2017 too.

    Glad to hear it worked for you.
    For some reason, it doesn't work for all systems,
    and then one needs to find an alternate path to get Net 3.5.

    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!
    Hello, I faced similar issue too. Most probably your windows is currently on .NET framework 4.6 (Advanced version) . It comes with windows 10 by default so you have to untick it first in your control panel before ticking & downloading the .Net Framework 3.5 otherwise it won't work. You can read this article ( Solved: How To Successfully Install .NET Framework 3.5 On Windows 10 - Infotechmagna) for step-by-step guide in doing this. That's what helped me solved mine too. Hope you'll have your problem solved.
