How to Fix Errors Without Downloading

Downloading DLL files from third-party websites exposes your computer to malware and version incompatibility issues. Instead, use these built-in Windows diagnostic tools to safely restore or repair the file.

1. Run System File Checker (SFC)

The SFC tool scans all protected system files and replaces corrupted or missing ones with a healthy cached copy.

Press Windows Key + X and select Terminal (Admin) or Command Prompt (Admin).
Type the following command and press Enter: sfc /scannow
Wait for the scan to reach 100% completion.
Restart your computer.

2. Run DISM Tool

If the SFC tool cannot find the file in its cache, the Deployment Image Servicing and Management (DISM) tool will fetch a fresh copy from official Windows Update servers.

Open Command Prompt (Admin).
Type the following command and press Enter: DISM /Online /Cleanup-Image /RestoreHealth
Allow the process to complete (this requires an active internet connection).
Run the sfc /scannow command one more time after DISM finishes.

3. Update or Reinstall Windows Mixed Reality / Camera Drivers

Because this file handles perception data, outdated hardware drivers can trigger the error.

Right-click the Start menu and open Device Manager.
Expand Cameras or Mixed Reality devices.
Right-click your device and select Update driver.
Alternatively, select Uninstall device, then restart your PC to let Windows reinstall it automatically.

4. Install Pending Windows Updates

Microsoft frequently patches bugs related to the Media Foundation framework through cumulative updates.

Press Windows Key + I to open Settings.
Navigate to Windows Update.
Click Check for updates and install all critical and optional packages.
Restart your system.
