• Next, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

2. Install or Repair DirectX via Official Microsoft Installer

The d3dcompiler.dll file is a core component of DirectX. Reinstalling DirectX from Microsoft will restore the file safely.

• If you are running an older game, locate the game's installation folder.
• Look for a subfolder named CommonRedist, DirectX, or Redist.
• Run the dxsetup.exe file found inside that folder to restore the exact DirectX files the game needs.
• Alternatively, run Windows Update (Settings > Update & Security > Windows Update) to ensure your system has the latest DirectX runtime payloads.

3. Update Your Graphics Card Drivers

Outdated GPU drivers can cause conflicts with DirectX compiler libraries.

• Press Windows Key + X and select Device Manager.
• Expand the Display adapters section.
• Right-click your graphics card (NVIDIA, AMD, or Intel) and select Update driver.
• Choose Search automatically for drivers or update via your GPU software (GeForce Experience / AMD Software).

4. Reinstall the Affected Software

If the error only happens with one specific game or application, the program's own local files might be corrupted.

• Open Settings > Apps > Installed apps.
• Find the problematic program and click Uninstall.
• Reinstall the program from its original disc, Steam, Epic Games Launcher, or official source.
