How to Fix DirectX 12 Not Working Errors on Windows 11: Step-by-Step Solutions

DirectX 12 is a vital component for running many games and multimedia applications on Windows 11. When it stops working, it can cause crashes, poor performance, or failure to launch programs.

This article will guide you through simple and effective steps to fix common DirectX 12 errors on your Windows 11 PC. Each step is explained clearly to help even beginners troubleshoot successfully.

By following these instructions, you can quickly identify the root cause and restore DirectX functionality without advanced technical skills.

Let’s get started with some quick checks before diving into detailed solutions.

Quick Note: Prerequisites and Initial Checks

Before attempting any fixes, ensure the following:

  • Your Windows 11 system is up to date. Updates often include important DirectX and graphics driver patches.
  • Your graphics card supports DirectX 12. Older hardware might not be compatible.
  • You have administrative rights. Some fixes require permission to install or modify system files.
  • Close all games and applications. Running programs can interfere with troubleshooting.

Step 1: Check Windows Updates

Windows Updates frequently include fixes for DirectX problems and driver compatibility. Here’s how to check for updates:

  1. Click the Start button and select Settings.
  2. Go to Windows Update on the left sidebar.
  3. Click Check for updates.
  4. If any updates are available, download and install them.
  5. Restart your computer after installation to apply changes.

Why this matters: Outdated system files can cause DirectX errors. Updating Windows ensures you have the latest fixes and improvements.

Step 2: Update Your Graphics Drivers

DirectX relies heavily on your graphics card drivers. Using incorrect or outdated drivers can cause issues.

Follow these steps to update your drivers:

  1. Press Win + X and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click your graphics card and choose Update driver.
  4. Select Search automatically for drivers and wait for Windows to find updates.
  5. If no updates are found, visit your graphics card manufacturer’s website (NVIDIA, AMD, Intel) to download and install the latest driver manually.

Why this is important: Updated drivers improve compatibility with DirectX 12 and fix bugs that may trigger errors.

Step 3: Run the DirectX Diagnostic Tool

This tool helps you check if DirectX is installed correctly and reveals any problems.

To run it:

  1. Press Win + R to open the Run dialog.
  2. Type dxdiag and press Enter.
  3. Wait for the tool to load.
  4. Look for the DirectX Version at the bottom of the System tab; it should say 12 or higher.
  5. Go to the Display tab and check for any notes or errors.

Why use this tool: It confirms if DirectX 12 is correctly installed and helps identify hardware or driver issues.

Step 4: Reinstall DirectX Runtime

Sometimes, DirectX files may become corrupted. Reinstalling the runtime can fix this.

Here’s how:

  1. Go to the official Microsoft DirectX End-User Runtime Web Installer page: Download DirectX Runtime.
  2. Download and run the installer.
  3. Follow the on-screen instructions to complete the installation.
  4. Restart your PC after finishing.

Why do this: The installer replaces missing or corrupted DirectX files without affecting your system negatively.

Step 5: Check for System File Corruption

Corrupted Windows system files can cause DirectX to malfunction. Using built-in tools like System File Checker (SFC) can help repair these files.

Follow these steps:

  1. Open Command Prompt as an administrator: press Win, type cmd, right-click Command Prompt, and choose Run as administrator.
  2. Type the following command and press Enter:
sfc /scannow

This process will scan and repair corrupted system files. Wait until it finishes completely.

Why this step matters: Fixing system file corruption can resolve underlying issues affecting DirectX performance.

Step 6: Adjust Graphics Settings

Sometimes, incorrect graphics settings or conflicts can cause DirectX 12 errors.

Try these adjustments:

  • Open Settings > System > Display > Graphics settings.
  • Set your game or app to use the High performance GPU if available.
  • Disable any unnecessary overlays or third-party software that interact with graphics (like screen recorders or FPS counters).

Why adjust settings: Ensuring the correct GPU and minimizing software conflicts helps DirectX run smoothly.

Alternative and Advanced Options

Update BIOS and Chipset Drivers

Outdated BIOS or motherboard chipset drivers can sometimes interfere with DirectX. Check your PC or motherboard manufacturer’s website for updates and install them following their instructions.

Use Compatibility Mode

If a specific game or application is causing DirectX 12 errors, try running it in compatibility mode:

  1. Right-click the program’s shortcut and select Properties.
  2. Go to the Compatibility tab.
  3. Check Run this program in compatibility mode for: and select an older Windows version like Windows 10.
  4. Click Apply and OK.

Frequently Asked Questions (FAQs)

What causes DirectX 12 not to work on Windows 11?

Common causes include outdated graphics drivers, missing Windows updates, corrupted DirectX files, incompatible hardware, or system file corruption.

Can I install DirectX 12 manually?

DirectX 12 comes pre-installed with Windows 11 and cannot be installed separately. However, you can reinstall related runtimes and update your system to fix issues.

How do I know if my graphics card supports DirectX 12?

Use the DirectX Diagnostic Tool (dxdiag) to check your DirectX version and graphics card details. Alternatively, look up your GPU model specifications on the manufacturer’s website.

Will updating Windows always fix DirectX errors?

Not always, but it often resolves compatibility problems by installing important patches and driver updates.

Is it safe to download DirectX from third-party sites?

No. Always download DirectX and related files from official Microsoft sources to avoid malware and corrupted files.

When Nothing Works

If you have tried all the above steps and DirectX 12 still does not work properly, consider these final options:

  • Perform a System Restore: Roll back your system to a previous state when DirectX was working.
