.NET Framework System Requirements

 

The tables in this topic provide the hardware, operating system, and software requirements for the .NET Framework 4.5 and its point releases (4.5.1 and 4.5.2) as well as the .NET Framework 4.6 and its point releases (4.6.1 and 4.6.2). Development environments that enable you to develop applications for the .NET Framework have a separate set of requirements.

For download information and links, see Installation Guide.

Notes:

  • On Windows 7 systems, the .NET Framework requires Windows 7 SP1. If you are on Windows 7 and have not yet installed Service Pack 1, you will need to do so before installing the .NET Framework.

  • The .NET Framework 4.5 is supported on the Windows Preinstallation Environment (Windows PE). Not all features are supported on Windows PE.

  • The .NET Framework 4 also supports the IA64 platform.

  • For all platforms, we recommend that you upgrade to the latest Windows Service Pack and install critical updates available from the Windows Update website to ensure the best compatibility and security.

  • On 64-bit operating systems, the .NET Framework supports both WOW64 (32-bit processing on a 64-bit machine) and native 64-bit processing.

Notes:

  • Windows Server 2012 includes the .NET Framework 4.5, so you don't have to install it separately. Similarly, Windows Server 2012 R2 includes the .NET Framework 4.5.1.

  • The .NET Framework is supported in the Server Core Role with Windows Server 2008 R2 SP1 or later, but isn't supported on Windows Server 2008 R2 for Itanium-Based Systems.

  • Windows Server 2008 SP2, the .NET Framework is not supported in the Server Core Role.

  • For all platforms, we recommend that you upgrade to the latest Windows Service Pack and critical updates available from the Windows Update website to ensure the best compatibility and security. Installation of the latest Windows Service Pack may be required on some operating systems.

  • On 64-bit operating systems, the .NET Framework supports both WOW64 (32-bit processing on a 64-bit machine) and native 64-bit processing.
