Most of its functions are essential when running multimedia applications, especially games, and they control elements like lighting effects and the application of textures.

Where to install d3dx9_39.dll?

Even though d3dx9_39.dll is bundled with the DirectX runtime, the DLL is often installed system-wide and located in the directory of the affected app or the Windows system directory.

How to fix the missing d3dx9_39 dll error?

Before going into the main solutions, you may try any of these quick procedures:

  • Restart your device – There are often little bugs that may trigger the error. A restart may be strong enough to shut them down and save you further troubleshooting.
  • Reinstall problematic apps – Your next call may be a reinstallation since the error may be triggered by the corruption of the game or app that needs the DLL.

1. Using a specialized tool

Many DLL tools are available to fix these errors. They can often replace a missing file or repair corruption.

Of the lot, Fortect is one of our top solutions. For Microsoft native DLLs like d3dx9_39.dll, it offers a 100% guarantee.

2. Manual download of the DLL

When the old DLL is corrupted, or in cases where it does not exist on the computer, you may manually download d3dx9_39.dll from trusted sources.

Once downloaded, you need to extract and add it to the same directory as the problematic application before launching the app.

Also, take care to only download DLLs from sites you trust because it is pretty common for malicious programs to be introduced to your system via a DLL.

3. Perform a System Restore

  1. Press Windows + R, type rstrui, and hit Enter.
  2. Click Next.
  3. Select a restore point and hit Next.

A system restore comes in handy because d3dx9_39.dll is native to the OS, and a restore would take the computer to a time it had all the files needed to run correctly.

4. Install DirectX End-User Runtimes (June 2010)

  1. Navigate to the download page for the runtime.
  2. Click on the Download button.
  3. Install the downloaded file and restart the computer.

Since the DLL is bundled with the runtime, getting a new installation also means you get the d3dx9_39.dll.
