Directx Runtime

[Barb Magario]

TheMicrosoft DirectX End-User Runtime installs a number of runtime libraries from the legacy DirectX SDK for some games that use D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, XACT, and/or Managed DirectX 1.1. Note that this package does not modify the DirectX Runtime installed on your Windows OS in any way.

IMPORTANT: Starting with Windows 10 October 2018 Update, RSAT is included as a set of "Features on Demand" in Windows 10 itself. See "Install Instructions" below for details, and "Additional Information" for recommendations and troubleshooting. RSAT lets IT admins manage Windows Server roles and features from a Windows 10 PC.

The DirectX End-User Runtime Web Installer (DXEUDRI) is a software package developed by Microsoft that simplifies the installation of DirectX, a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming.The package consists of a collection of DirectX libraries and components required to run several graphical interfaces on Windows.The runtime includes support for a wide variety of hardware and software, including graphics cards, sound cards, and other hardware, as well as support for a range of programming languages and APIs.Includes DirectX 9.0, 10 and 11The main download of DirectX, dxwebsetup.exe will download all currently available versions of DirectX and its updates including DirectX 9.0, 9.0c, 10 and 11. This particular version was released in June 2010.After extracting the files in a directory, you can run DXSETUP.exe which will update a Windows 7, Windows 8 or Windows 10 system will all of the required libraries to run DirectX-compliant applications.Not all of these libraries are installed by default on Windows 10, so DirectX End-User Runtime Web Installer application may be necessary.This web installer includes many of the fixes for errors encountered with older versions of the installation for a variety of graphics cards such as MSI, NVIDIA, AMD.Note about the installerDXEUDRI also automatically detects the hardware configuration of the user's PC and only downloads the components of DirectX that are needed for the optimal performance of their games.Features of DirectX RuntimeAudio: Spatial sound for immersive gaming experiences.Compression: Improved compression of game data.Developer Tools: Optimized tools for game developers.DirectCompute: Support for GPGPU programming.DirectX Raytracing: Cutting-edge raytracing capabilities.Graphics: High-performance real-time 3D graphics.Hardware Support: Enhanced support for modern hardware.Multi-GPU: Support for multiple GPUs.Multi-Threading: Improved multi-threaded performance.Networking: Network gaming and real-time communication.SDK: Robust Software Development Kit.Security: Improved security features.Shader Model: Enhanced support for shader models.Video: Improved video playback and streaming.Compatibility and LicenseDirectX Runtime is provided under a freeware license on Windows from components with no restrictions on usage. Download and installation of this PC software is free and 9.29.1974.1 is the latest version last time we checked.

CrossOver has its own implementation of DirectX, at least of the important low level components like ddraw.dll, d3d8.dll, d3d9.dll, dsound.dll, dinput.dll. Games complain that they can't find DirectX for many different reasons, and often the error doesn't have anything todo with directx at all. Most of the time one of those things here happens:

-> High level libraries are missing: There are some dx libs which CrossOver doesn't implement (yet), and which are supposed to be installed by the game, even on Windows. Those are libraries like d3dx9, d3d8x and similar. You can get them by installing the DirectX runtime in CrossOver, there is an installer profile for this.

-> Missing features: CrossOver can only offer to the game what the graphics card offers. E.g. if your card doesn't have shader support, we cannot give shaders to the game. Especially on MacOS we've disabled shader model 2.0 and 3.0 support due to driver bugs. I've explained how to enable them in other threads, search for "useGLSL".

Depending on the version of Windows you're using, you might not be in need of a new version of DirectX. See the section below these steps to confirm that DirectX will work for your computer. If you're not sure which version your computer has installed right now, there are instructions for doing that at the very bottom of this page.

DirectX is a collection of application programming interfaces (APIs) required to play video games on a Windows PC. It allows the games you play to "talk" to your computer's hardware, such as the graphics card, sound card, and memory.

Since DirectX is a necessary part of Windows, there's no official way to uninstall it. But you may be able to roll back to a previous version of it. Open System Restore and choose a restore point that was created before DirectX was updated, then use the DirectX Diagnostic Tool to check and make sure you're on the earlier version.

If you download Microsoft's DirectX End-User Runtime Web Installer, it installs a number of runtime libraries from the legacy DirectX SDK automatically. You may need these to run some video games that use D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, XACT, and/or Managed DirectX 1.1. Installing this package won't modify the DirectX Runtime already installed on your PC.
