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.

    Yeah, and not even Microsoft's own err.exe can resolve what this error code means.

    I have the exact same problem when turning on the .NET Framework 3.5 on ARM, "Windows couldn't complete the requested changes, Error code: 0x800F0950".  Really hoping for a fix

    I have a different error number when attempting to install it on my Parallels 16 VM:

    Image

    Edit: Disregard that, it gave me the error because for some reason, the virtual Ethernet controller was disabled.

    Edit 2: Now it's 0x800F0950.

    Edit 3: Found a possible fix at: .NET Framework 3.5 installation errors - Windows Client | Microsoft Docs - The group policy specified in the first troubleshooting step was disabled, trying again with it enabled.
