Net Framework 4.0 Redistributable 64 Bit |work| Jun 2026
The Microsoft .NET Framework 4.0 Redistributable (64-bit) is a critical software component that provides the Common Language Runtime (CLR) and base class libraries required to execute applications built for .NET Framework 4.0 on 64-bit Windows operating systems. While functionally stable, it is and has been superseded by newer, backward-compatible versions (.NET 4.5, 4.6, 4.7, 4.8). New deployments should target .NET Framework 4.8 unless legacy application constraints mandate version 4.0.
The Essential Guide to .NET Framework 4.0 Redistributable (64-Bit)
The 64-bit (x64) version specifically targets 64-bit operating systems. While 64-bit Windows can run 32-bit (x86) applications via the WoW64 (Windows on Windows 64-bit) subsystem, running a native 64-bit application requires the 64-bit .NET runtime. The 64-bit redistributable ensures that applications can leverage the full memory space and architectural benefits of a 64-bit processor. System Requirements for Installation
Several PC games from the early 2010s (e.g., early versions of Minecraft (Java Edition launcher), StarCraft II, or SimCity 2013) used .NET 4.0 for their launchers or auxiliary tools. Without the redistributable, these launchers crash silently or throw runtime errors.

Up to 2 GB of available space for installation. How to Install the .NET Framework 4.0 Redistributable Follow these steps for a clean installation. Step 1: Download the Offline Installer
Microsoft ended mainstream support for .NET 4.0 on January 12, 2016. Extended support ended on April 12, 2022. Do not install 4.0 on internet-facing servers. Use it only for internal legacy applications isolated from the internet. Always apply the latest available security updates via Windows Update (which for 4.0 means updates to the 4.x runtime family).
This contains everything in the Client Profile, plus components needed for server applications, such as ASP.NET and advanced database connectivity ( System.Data.OracleClient ).
Microsoft offered two "profiles" for .NET 4.0: the and the Full Profile . The Client Profile was a smaller, 41 MB package containing only the components most common to client applications, intended for faster deployment. However, the Full Profile (the 48.1 MB dotNetFx40_Full_x86_x64.exe ), which includes all features such as server-side components like ASP.NET, is what most users ultimately need to ensure complete compatibility. The Microsoft
