In the extraction directory, run DXSETUP.exe, which will install all components of DirectX 9.0 / legacy DirectX SDK. Specify a directory and extract the files. On the Standalone installer, after you run it, it will ask you to specify a directory where the installation files should be extracted. You can download the latest version of DirectX 9.0c, the June 2010 update (now called the 'legacy DirectX SDK' by Microsoft), from Microsoft's website: Standalone Installer / Web Installer. Maybe it is also possible to just install the latest one from June 2010, i'm not sure if it contains the earlier versions too.

This gives you a clue of what to search for, the keywords directx Mar2009 lead me to the microsoft download page.

The list below shows the available DirextX-9 versions, the version can be found at the third column. If the missing file is for example d3dx9_41.dll, it means that DirectX-9 version 41 is required. To find the correct version i analyzed the error message. The exact version depends on the file which is required by your application, in my case it was directx_mar2009_redist.exe. You can download the 'DirectX end user runtimes' from Microsofts website. Did DirectX 9 improve the performance of the game for you or it feels and acts exactly the same as before.Had the same problem when i tried to run an older game on Windows-10, it complained about a missing dll d3dx9_41.dll. 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.
