How to Update DirectX

Last Updated: April 11, 2021

Microsoft DirectX is a set of Application Programming Interfaces (APIs) that provide Windows programs and apps with the support needed to power video games and game programming on most Microsoft platforms. DirectX is normally updated automatically through routine Windows Updates, but can also be downloaded and updated manually for select versions of Windows.

Troubleshooting DirectX Updates

1
Try installing DirectX End-User Runtime if you receive the following error when installing an application or game that requires DirectX 9: “The program can't start because d3dx9_35.dll is missing from your computer. Try reinstalling the program to fix this problem.” Installing the DirectX End-User Runtime program can often help resolve this error.

- Click on “Open” or “Run this program from its current location” to install the program and resolve the error.

Run the DirectX Diagnostic Tool if you experience problems when playing games or movies after installing DirectX updates. In many cases, this tool can help identify the source of problems associated with DirectX.^{[3]

Try updating the drivers for your video card, or replace the video card itself if updating DirectX fails to resolve problems with certain apps and programs. In some cases, a faulty video card can prevent DirectX from working efficiently.^{[4]
