What is error 0x800f0950 in Windows 10

The appearance of the dreaded 0x800f0950 installation error when installing .Net Framework 3.5 in Windows 10, as well as the latest version of Windows 11, is a big headache. The error occurs to many users when they try to install the .NET 3.5 Framework through a traditional installer or run a game or program that requires it.

The error message comes in the form of a short message “The following feature cannot be installed” along with a solution that does not work for users.

But before going directly to the solutions, it is worthwhile to get acquainted with the most common causes of error code 0x800f0950 on Windows computers.

What is a .Net Framework

The .NET Framework is a software framework used by many Windows applications. For developers, the .NET Framework provides a unified programming model for creating applications. Some programs developed with a particular version of Visual Studio require a particular version of the .NET Framework. Many companies develop their applications to run on the .NET Framework, and those applications are designed for a particular version.

Typically, Windows 8.1 and 10 come preloaded with the .NET Framework 4.5 and 4.6. But applications developed using the .Net Framework 3.5 won’t work on Windows 10 and 8.1 systems unless the .Net Framework 3.5 is installed on your system.

What causes error 0x800f0950

  • The Windows component is corrupted.
  • Windows installer components are corrupted.
  • Due to the lack of .NET Framework 3.5 or 4.8.
  • Outdated Windows build on Windows 10 and 11.
  • Remains of previously installed .NET Framework cause conflicts.
  • The .NET Framework is already loaded and waiting to be installed via WU.
