Unable to find d3dx9_34.dll system file

Asked By 0 points N/A Posted on -


I have installed a PC game in my Windows 7×64 machine. It was installed perfectly but when I tried to play the game I was given an error.

The error was: Missing d3dx9_34. dll

However, when I was searching for the file, it exists on the System32 folder. I already have the 64bit dll but the pasting seems not to be working. Is there a way to register this file?

Thanks all!

D3dx9_34.dll-related errors are very common, especially when some applications are running that Microsoft DirectX is required to be properly displayed. Games applications are frequently required to run Microsoft DirectX.

There are two reasons why this error appears.

  1. D3dx9_34.dll is removed;
  2. Error in registry;

The solutions could be the following.

  1. Run a registry scan. You could find it at this link of free registry scan for Windows.
  2. You also should download D3dx9_34.dll for free at the above link. It is a Zip file.
  3. Then extract and install the downloaded files to the directory of Microsoft DirectX. It should be located at C:/Windows/System32.
  4. If the files are already existed, overwrite them because they may be corrupted or damaged or misused.
  5. Reboot again.

Hope the above could help. Thank you for your attention.

It means that you do not have a correct version of DirectX.

You need to install the latest version of DirectX 9.0C (found on the game disk or at https://www.microsoft.com/en-us/). This is true even for Vista owners using DX10.
