How to Fix D3dx9_33.dll Errors

Important Note: Do not, under any circumstances, download the d3dx9_33.dll DLL file individually from any DLL download site. There are a number of different reasons that downloading DLLs from these sites is never a good idea.

Note: If you've already downloaded d3dx9_33.dll from one of those DLL download sites, remove it from wherever you put it and continue with the following steps.

  1. Restart your computer if you haven't yet done so.

    The d3dx9_33.dll error might be a fluke or one-time issue, and a simple restart could clear it up completely. It's unlikely this will fix the problem, but restarting is always a good first troubleshooting step.
     
  2. Install the latest version of Microsoft DirectX. Chances are, upgrading to the latest version of DirectX will fix the d3dx9_33.dll not found error.

    Note: Microsoft often releases updates to DirectX without updating the version number or letter, so be sure to install the latest release even if your version is technically the same.

    Note: The same DirectX installation program works with all versions of Windows including Windows 10, 8, 7, Vista, and XP. It will replace any missing DirectX 11, DirectX 10, or DirectX 9 file.
     
  1. Assuming the latest DirectX version from Microsoft doesn't fix the d3dx9_33.dll error you're receiving, look for a DirectX installation program on your game or application CD or DVD. Usually, if a game or ​another program utilizes DirectX, the software developers will include a copy of DirectX on the installation disc.

    Sometimes, though not often, the DirectX version included on the disc is a better fit for the program than the latest version available online.
     
  2. Uninstall the game or software program and then reinstall it again. Something may have happened to the files in the program that work with d3dx9_33.dll and a reinstall could do the trick.
     
  1. Restore the d3dx9_33.dll file from the latest DirectX package. If the above troubleshooting steps haven't worked to solve your d3dx9_33.dll error message, try extracting the d3dx9_33.dll file individually from the DirectX package.
     
  2. Update the drivers for your video card. While it's not the most common solution, in some situations updating the drivers for the video card in your computer could correct this DirectX issue.
