# Install DirectX

*DirectX provides the graphics files that games and overlays depend on. Windows 10/11 already includes DirectX 12, but many games and overlays still need the **older DirectX 9/10/11 files** that are only installed by this package — install it even if your system is up to date.*

{% hint style="info" %}
**Install this if you see errors like:**

* `d3dx9_43.dll is missing`
* `d3dx11_43.dll is missing`
* `xinput1_3.dll is missing`
* `D3DCOMPILER_43.dll is missing`
* Overlay/ESP not rendering in game
  {% endhint %}
