9 Fixes: ResampleDmo.DLL Was Not Found Error in Windows 11 / 10

What is Resampledmo.dll?

ResampleDmo.DLLis a Dynamic Link Library (DLL) used by Windows for audio resampling, which means converting audio from one sample rate to another (for example, from 44.1 kHz to 48 kHz) to ensure compatibility between different audio devices, applications, and output formats.

The file is part of the DirectX Media Object (DMO) framework and functions as an audio resampling filter within the Windows audio pipeline. It works with core components such as Windows Media, DirectSound, and Media Foundation to maintain stable and consistent audio playback across the system.

Where it’s used:

• System sounds (notifications, alerts, startup sounds)
• Audio playback in videos, games, and media players
• Audio format conversion when the source sample rate does not match the output device
• Third-party applications that rely on Windows audio APIs (such as DAWs, screen recorders, video editors, and streaming software)
• Real-time audio processing where resampling is required to avoid distortion or playback errors

Where it’s located:

The file is usually stored in the Windows system directory:

• C:\Windows\System32\resampledmo.dll

On 64-bit Windows, a 32-bit version may also exist in:

• C:\Windows\SysWOW64\resampledmo.dll

The file is digitally signed by Microsoft, indicating it is an official system component.

Why "The Code Execution Cannot Proceed Because ResampleDmo.DLL Was Not Found" Error Occurs?

This error appears when Windows or an application cannot locate "resampledmo.DLL", a core system file required for audio processing. The most common causes include:

1. Missing or deleted system file: The DLL may have been accidentally removed by the user, a cleanup tool, or third-party software.

2. Corrupted Windows system files: File system corruption, improper shutdowns, or disk errors can damage resampledmo.dll.

3. Incomplete or failed Windows update: An interrupted Windows update may fail to register or restore required system DLLs.

4. Incorrect application installation: Some programs rely on Windows audio components; if installation fails, the DLL may not be properly referenced.

5. Malware or antivirus interference: Security software may mistakenly quarantine resampledmo.dll, or malware may replace or delete it.

6. Wrong system architecture mismatch: Using a 32-bit application on a 64-bit system (or vice versa) can trigger DLL lookup failures if paths are incorrect.

7. Damaged Windows audio components: Issues with DirectX, Media Foundation, or Windows Audio services can prevent the DLL from loading correctly.

When this error occurs, audio playback may fail, applications may not launch, or Windows may display repeated startup warnings.

How to Fix "ResampleDmo.DLL Was Not Found" on Windows 11 or 10?

To resolve the "ResampleDmo.DLL was not found" windows 11 effectively, we can start with the easiest fixes and proceed to more advanced ones only if necessary. More details are introduced below.

Before making any changes, restart your PC. Temporary system glitches, incomplete background updates, or locked system files can sometimes trigger DLL errors. A reboot refreshes Windows services and may restore normal file loading automatically.

2. Check Windows Recycle Bin

Since ResampleDmo.DLL can be accidentally deleted by the user, system cleanup tools, or even antivirus software, it’s worth checking the Recycle Bin first:

Open the Recycle Bin from the desktop or File Explorer. Look for a file named ResampleDmo.DLL. You can use the search bar at the top-right corner to find it quickly.If the file is found, right-click → Restore. This will return it to its original location.

After restoring, restart your computer to ensure Windows can properly load the DLL.

If you can’t find the ResampleDmo.DLLin Recycle Bin, also check your antivirus quarantine. Sometimes security software mistakenly flags system DLLs as threats and moves them to quarantine. Restore the file from there if necessary.

Step 1. Open your antivirus or Windows Security → Protection history.

Step 2. Look for any quarantined system DLL files and restore them if found.

4. Repair Corrupted System Files (SFC)

Corrupted or missing system files are one of the most common reasons for the "ResampleDmo.DLLwas not found" error. Windows includes a built-in tool called System File Checker (SFC) that scans and automatically repairs such issues.

Step 1. Press "Win + S", type "cmd", then right-click → "Run as administrator" to open an elevated Command Prompt.

Step 2. In the command window, type the command and press Enter: sfc /scannow

The scan will start automatically. Do not close the window until it reaches 100% — this may take several minutes depending on your system.This tool scans and repairs missing or corrupted system DLLs automatically.

5. Restore Windows Image Using DISM

If SFC cannot fully repair missing or corrupted system files, the Deployment Image Servicing and Management (DISM) tool can fix deeper Windows system image issues. DISM repairs the underlying Windows component store, which SFC relies on to restore files like resampledmo.dll.

Run the following commands one by one in Command Prompt window, pressing Enter after each:

DISM /Online /Cleanup-Image /CheckHealth: quickly detects if the system image is damaged.

DISM /Online /Cleanup-Image /ScanHealth: performs a more thorough scan and identifies issues.

DISM /Online /Cleanup-Image /RestoreHealth: repairs any detected problems using Windows Update or local sources.

Wait for each process to complete. Depending on your system, this may take 5–20 minutes per command. Do not close the window during the scan.Once DISM finishes, run SFC /scannow again to ensure all missing or corrupted files (like resampledmo.dll) are fully restored. This combination usually resolves "ResampleDmo.DLL was not found" errors caused by system corruption or failed updates.

6. Update Windows to the Latest Version

Sometimes, the "ResampleDmo.dll was not found" error occurs because your system is missing updates that restore or register critical Windows components.
