DLL errors are hands-down one of the most complicated and annoying errors you will get while running on Windows. Sometimes, fixing the DLL error itself is even more complicated than just replacing the DLL file and even when you do manage to fix some of these problems, there’s no guaranteeing that they won’t pop up the next time you launch a program or restart your PC.

This error could pop up as “D3dx9_43.DLL is missing” or “D3dx9_43.DLL Not Found”, and is usually caused by problems with the DirectX. You will receive either of the above errors most commonly when you are starting to start a gaming or graphic-intensive software. Although strongly associated with gaming, the D3dx9_43.DLL error can pop up from any program that makes use of the Microsoft DirectX feature.

Sometimes, these errors may open when you try to launch the software, other times, they occur when the software or game is already in play. Noting what point these errors pop up will be highly instrumental when troubleshooting your PC for solutions to the error.

How to fix D3dx9_43.DLL and Xinput1_3.DLL errors

To fix any of the above errors, try out the following steps:

  1. First, restart your computer and try to run the program again. This will help you to determine if the DLL error is real or was just a fluke.
  2. Install the latest version of the DirectX program. This update will most likely come with many component files of the DirectX and should fix the “D3dx9_43.DLL not found” error. This latest DirectX software should work for all versions of Windows and will replace any missing DirectX9, DirectX 10 or DirectX11 files.
  3. Should the installation of the latest version of DirectX above not work, the next step is to open the CD/DVD or source file for the application setup you are trying to run. Install the accompanying DirectX. This could work as sometimes, programs come with versions of DirectX that the publisher has deemed most suitable for the game or application.
  4. If this doesn’t work still, opt to uninstall and reinstall the software or game. Ensure that you restart after the uninstall to ensure that any files are not still lingering, then do a fresh copy install.
