SOLVED: Cannot Install .NET 3.5 On Windows 10 Error 0x800F0906 and 0x800F081F

If you are running Windows 10 and need to install something old that requires .NET 2 or .NET 3.5 you will likely follow the instructions to install it from PROGRAMS AND FEATURES > TURN WINDOWS FEATURES ON OR OFF > .NET FRAMEWORK (INCLUDES .NET 2.0 and .NET 3.0) but then find you receive  errors like 0x800F0906 and 0x800F081F .  This is frustrating.  Fortunately the solution is simple IF you have a Windows 10 source disk:

You can install .NET 3.5 by bringing up a CMD window (don’t forget to right click and RUN AS ADMININISTRATOR) and then type either:

Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccess

This has been a problem since Windows 8 and Microsoft really needs to fix it.  I have to do this command line install 100% of the time I need old .NET versions.

  • Thanks , after using an dvd image of windows 10 i was able to add the framework 3.5 to windows 10 without any error.
    thanks a lot

    • Hi Dennis;

      I have run this literally dozoens of times on different builds of Win10 without issue. I would try running a System File Checker sfc /scannow to make sure the system is healthy. I hope that helps

    • Hmmm... that is the point to this post are you sure you ran the CMD prompt as an admin and the typed Dism /online /enable-feature /featurename:NetFx3 /All /Source::\sources\sxs /LimitAccess
      changing to 'D' most likely so it looks like Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

  • i need a Microsoft dot net framework 3.5 . Because i can't download and install this framework.then
    error code is: 0x800F0906. please give a solution for this issue And i can't do windows update. i installed windows 8.1 single language

    • Does the command in the post Dism /online /enable-feature /featurename:NetFx3 /All /Source::\sources\sxs /LimitAccess not work for you?

        • I just ran this again without problem on a Windows 10 1803 PC. If I had to guess I would say you are not setting the drive letter. Dism /online /enable-feature /featurename:NetFx3 /All /Source:d:\sources\sxs /LimitAccess In my case I was using a DVD that showed up as drive D . Have you set the drive letter?
