Windows 11 error code 0x800f0950 occurs when you try to install the .net framework 3.5 relying on the conventional installer. It also happens when you try to open a program or video game that needs .NET 3.5 framework.
There is also a chance that the target .net framework has already been downloaded and has been pending to be installed within the Windows update. If so, if you try to install the same framework individually, you can see the error 0x800f0950.
