This distro doesn't just update DX9, but also updates DX10/DX11.

If you have any troubles, leave a comment and let me know of YOUR experience. You can download the old DirectX 9 from here:

The link provided below is from Microsoft’s official website. Installing DirectX 9 does not hurt your system, it will not break anything. You can get a Windows 10 Pro for $28 from Kinguin (use code “vulkk” for extra 3% OFF) – I got a copy myself from them :) There is no overriding or replacing, the installation just adds another layer. If the game can benefit from DirectX 11 or 12, it WILL use those. By doing that, you DO NOT remove the DirectX 12, no, it just installs extra libraries and gives the game you play an option which ones to use. Download the file from the link I have provided below (leading to the official Microsoft website) and install with no manual changes during the process.
