Download Microsoft .NET Framework 4.5 (Offline Installer)

Microsoft .NET (MS dot Net) is a programming framework used to develop different programs, games, and many other applications. This Microsoft-developed programming infrastructure is used in building, deploying, and running applications and services that use .NET technologies, such as desktop applications and Web services. It is also used to run programs made with Visual Studio using this framework. .NET Framework packages primarily run on the Microsoft Windows operating system.

.NET Framework 4.5

The Microsoft .NET Framework 4.5 was first released on 15 August 2012 by Microsoft. This version is available for download directly from its official source as an online installer and offline installer. Now you can download the latest .NET Framework 4.5 standalone Offline Installer setup directly from the Microsoft website. The Microsoft .NET Framework version 4.5 includes several new features, fixes, and improvements compared to previous versions.

The latest Microsoft .NET Framework runtime version 4.5 is available for Windows 7 Service Pack 1 (32-bit), Windows 7 SP 1 (64-bit) Windows 8.1, and Windows 10, and all server platforms starting with Windows Server 2008 R2 Service Pack 1. The Windows 10 version 1903, also known as Windows 10 May 2019 Update includes Microsoft .NET Framework version 4.5 by default.

The .NET Framework 4.5 installer is available in both online (web installer) and offline installer modes. The main difference between the online and offline installer is that the online or web Installer is a very small setup file and it needs an active Internet connection during installation as it requires downloading the necessary data, files, and components from its servers. On the other hand, the NET Framework 4.5 offline installer is a standalone setup that is quite larger in size than the web installer as it includes all the necessary data, files, and components and it doesn’t require any internet connection during installation the software on PC.

This version of the .NET Framework is a highly compatible, in-place update to the .NET Framework 4. By using the .NET Framework 4.5 together with the C#, Visual Basic, or F# programming language, you can write Windows apps. It includes significant language and framework enhancements for C#, Visual Basic, and F#. 

Note: Windows 8 and Windows Server 2012 include the .NET Framework 4.5. Therefore, you don’t have to install this software on those operating systems.


This release has reached end of life, which means it is no longer supported. Therefore, we recommend moving to a supported release, such as .NET Framework 4.8.
