How to install the latest version of DirectX - Microsoft Support

There is no official standalone offline installer for DirectX 12 on Windows 10. Unlike older versions, DirectX 12 is integrated directly into the Windows 10 operating system and is updated exclusively through Windows Update. Helpful Review of Current "Installers"

Even with the offline installer, you might encounter issues. Here is how to fix them.

Why Do Games Ask for DirectX Then?

If DirectX 12 is already built-in, why do games (even modern ones) often pop up an installation window for DirectX when you first launch them?

There are two reasons for this:

  1. Legacy Files (DirectX 9): Many modern games still rely on older DirectX 9 libraries to function. While Windows 10 includes DirectX 12, it does not include every single legacy file from the DirectX 9.0c era. When a game installs "DirectX," it is actually installing a collection of legacy DLL files (like d3dx9_*.dll) into the game's folder, not updating your DirectX 12.
  2. Specific Hardware Drivers: The DirectX installer that runs with games is checking for specific hardware interface drivers that might not be active on your generic Windows 10 installation.
