HI All,

Cannot install .net framework 3.5 on Windows 10 on ARM Insider Preview image, is it not supported?

I used the Windows 10 ARM insider Preview "VHDX" to setup this Windows.

From link:

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewARM64

I tried DISM/UI also installation failure with 0x800F0950, I tried to find this ARM version ISO to install from source.

However, there is no ISO provided (just has the VHDX)

Would like to confirm is Windows 10 on ARM Insider Preview image not supported .net framework 3.5 to be installed? Thanks.

    Thanks. I updated to the latest Build and it's fixed.

    Great! I'm glad to hear that.

    By the way, a new build just released today: 21332.

    Hi aLaw_

    Is your device ARM64? Can you list the make and model of your computer?

    Hi @aLaw_ ,

    A few questions:

    1. Are you running the latest Insider Preview? Even though the VHDX is older, it's best to enroll in the Windows Insider program from the Updates & Security menu in Settings, then upgrade to the latest build.
    2. If yes, Have you modified any group policy settings or made any manual settings changes to Windows Update? Usually these will cause problems with feature installation/updates.
    3. Do you have any proxies enabled on your system?
    4. When you go to install the .NET Framework 3.5 feature in the optionalfeatures program, does it give you an option to download the required files from Windows Update?

    I know where where is Program and Feature to add .net Framework 3.5

    I said there is an error when install 0x800F0950 via the "add Windows feature" and I tired use DISM command also but failed.

    I searched google and find it seem only happy on "Windows 10 ARM insider Preview "VHDX" version"

    This version:

    https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewARM64

    Are you tried this version before?
