Download Free for Windows

DirectX Runtime offers an innovative set of APIs for connecting software to system hardware. It enables the installation of legacy libraries to run various classic apps and games, such as D3DX9, D3DX10/11, and XACT, among others. It is the best solution to run old games and multimedia on your modern PC smoothly and reliably.

The free-to-use utility deals with multiple advanced techniques, including advanced rendering, real-time audio, Direct3D, and hardware acceleration, to enable developers to develop and deliver enriched graphics for different hardware setups. 

What is DirectX Runtime?

DirectX is one of the powerful programs developed by Microsoft Corporation that offers effortless services to manage multimedia, including games, programming, and videos. The term “Direct” is used by the company because it manages all APIs, such as Direct3D, Direct Draw, Direct Sound, Direct Play, and “X” stands for a huge collection when Microsoft developed their gaming console, while giving it the name “Xbox” to show that the console is based on the DirectX technology.

DirectX End-User Runtime is the latest version of 9.0c and the successor of all old Direct Redistributable versions. It helps in reducing the download size, and unlike older versions, it requires an internet connection.

DirectX End-User Runtime Features

Legacy Technologies Integration

Most of the modern Windows versions lack multiple DirectX libraries by default. So, we need to install DirectX on modern operating systems to run classic applications and games. It helps to save from the bother of installing older operating system versions or emulating them on a virtual machine.

DirectX version Assessment

You can check the available version of DirectX on your system to determine whether it needs to be updated or not. You can use two methods for the purpose.

  • Use your command line to run the dxdiag utility, as it will give you all the details of DirectX
  • Use DirectX Version Checker, a tool that not only gives information about the installed version, but also other details such as DirectX Debug Levels, DirectShow Filters, DirectInput Devices, and so on.

Seamless Compatibility

The innovative utility offers seamless compatibility with all types of Windows operating systems, including Windows 11, Windows 10, Windows 8/8.1, Windows 7, Windows XP, and Windows Vista. 

Simple Installation

The app offers a quick and smooth installation process within a few clicks, and within a minimum time. If you may have to face any problem such as “d3dx9_39 .dll not found”, “dsetup.dll error”, or d3dx9_43.dll missing”, you can fix any installation issue by installing the one set of DirectX Runtimes, and others will automatically install on your system.

DirectX for Developers

DirectX is the best solution that is specifically designed for gamers, but it also helps developers while offering valuable assistance, specifically the developers who deal with apps that depend upon legacy libraries. It makes it possible to set up the legacy libraries on the apps without interfering with the modern DirectX environment, and offers effortless integration to enhance performance. The developers also have the opportunity to add a multi-language redistributable for managing the terms used by developers for using the Redistributable. 

Update DirectX

The updating process for DirectX End-User Runtime is very easy and smooth, as you need only run DirectX End-User Runtime Web Installer while making sure there wouldn’t by no risk or malicious threat. The smart engine available on DirectX Runtime offers a quick process of analyzing the already installed version, and displays a list of versions available on Microsoft’s server. It will offer the non-existent updates integrated into your local items, and install the latest one. You need to waste time on manual searching; instead, the installer not only installs the latest version, but also removes obsolete files from your system. 

Seamless Integration to DirectX Versions

The DirectX Runtime offers seamless integration to all DirectX versions along with 32-bit and 64-bit operating systems. The integrated versions are DirectX 9, DirectX 10, DirectX 10.1, DirectX 11, and DirectX 12. The DirectX Runtime doesn’t replace the version of DirectX; it only offers a runtime environment for classic games and other additional elements of the DirectX SDK. 

Simple & Lightweight

The lightweight utility with very low consumption of system storage offers a very simple and smooth process, even for non-technical users. It only optimizes your modern operating system without replacing the modern frameworks.
