Whenever I try to install .NET Framework 3.5, I get the error: 0x800f0954. I have tried to even reset the registry value for UseWUServer but it didn't work.

Had tried to update my Windows 10 to the current version which is 22H2 but it didn't accept the installation of the .NET framework.

    Hi there,

    Please try John's instructions for the .Net Framework issue. If disabling the UseWUServer registry value didn't help, see Method 3 (using the ISO) Error 0x800F0954 Installing .NET Framework 3.5.

    Had tried to update my Windows 10 to the current version which is 22H2 but it didn't accept the installation of the .NET framework.

    It would help if you posted the setup error code you received. Please download SetupDiag and run it. The tool collects the setup logs and saves them into a zip file named Logs.zip on your desktop. Upload the file to your OneDrive, Dropbox, or any other cloud hosting account and share the link here.

    This helps no one.

    The question is specifically about error code 0x800F0954

    Your answer is about generic .Net installs.

    Please read the question properly before answering next time.

    Hello all,

    In my case, .net 3.5 installation only works via Powershell.

    You need a Win10/11 iso - it must be open.

    Then run Powershell as admin and enter the following command:

    Dism /online /enable-feature:NetFx3 /All /Source: E:\sources\sxs /LimitAccess

    "E:" stands for the drive letter in which the ISO file is opened.

    Execute the command with Enter.

    Then restart the client and it should work.
