DirectX 9.0c is a collection of application programming interfaces (APIs) developed by Microsoft. It is designed to enhance and optimize multimedia experiences, primarily for Windows-based systems. This software package provides developers with a comprehensive suite of tools and resources to create cutting-edge graphics, audio, and multimedia applications.

The latest version of the Microsoft Windows Gaming API delivers Microsoft's powerful new High-Level Shader Language (HLSL) and features its most-advanced suite of design tools for the development of rich multimedia elements such as full-spectrum color graphics, video, 3D animation, and enhanced audio capabilities.

Some applications and games require DirectX 9 (End-User Runtime Web Installer) for PC. However, your computer includes a more recent version of Direct X. If you install and then run an application or game that requires the app, you might receive an error message such as "The program can't start because d3dx9_35.dll is missing from your computer. Try reinstalling the program to fix this problem."

DirectX 9.0 (DX9) for Windows XP and Windows Server 2003 introduces significant improvements across its suite of APIs. DirectSound offers new audio capabilities, DirectShow accelerates video rendering hardware, and Direct3D enhances low-level graphics programmability with new programmable vertex and pixel shader 2.0 models. DirectX9 End-User Runtime Web Installer is supported in Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP!
