How to Fix the D3D9.dll Error on Your PC

Step 1 – Update DirectX

One way to solve the error is to update Microsoft DirectX. The application was designed to help Windows-based computers in properly running multimedia elements.

To update DirectX, go to Microsoft website and find the available upgrade or download for it. There are two ways to get the update, either you click Open or Run to process the upgrade from its current location, or you can instead copy and then download the upgrade onto the computer. By clicking save and opening it, the installation will automatically proceed. Make sure to follow instructions accordingly.
