Solved: MFReadWrite.dll Missing on Windows 11

MFReadWrite.dll is a core shared dynamic link library (DLL) or Windows, including the latest Windows 11. It’s used by Microsoft’s Media Foundation framework, which provides various multimedia-related functionalities and services, including encoding, decoding, streaming, and playback of audio and video, often via Windows Media Player and within games.

I first got a MFReadWrite.dll error while trying to play Roblox, with the message: The code execution cannot proceed because MFReadWrite.dll was not found. Reinstalling the program may fix this problem.

Upon clicking OK, the game simply closed and failed to launch.

After heavily researching the problem, it can occur across multiple programs and games with different variations of the same missing DLL error.

Here’s everything you need to know to diagnose and repair the MFReadWrite.dll was not found error on Windows 11.

What does MFReadWrite.dll missing on Windows 11 mean?

When an error related to MFReadWrite.dll pops up when launching an app or game, it either means the DLL file has somehow been deleted from your computer, it exists but has been damaged and can no longer function, or other system corruption such as a broken Windows Registry is preventing Windows from successfully locating the file, even when it exists.

It can also be linked to a corrupted or missing Windows Media Feature Pack.

Because MFReadWrite.dll is integral for various Windows media tasks, it is shared by many different system programs like Windows Media Player, and third-party games and software. Essentially, any app that needs to play audio or video could fail without MFReadWrite.dll.

In my experience, most of the reasons MFReadWrite.dll goes missing or gets corrupted include:

In my experience, most of the reasons MFReadWrite.dll goes missing or gets corrupted are because:

Windows Update Failure – When a Windows update fails or is otherwise interrupted, it can cause files like MFReadWrite.dll to go missing. This is a common issue when upgrading to Windows 11.

Malware Infection – Viruses and other malware target Windows to make it unstable. Shared DLLs like MFReadWrite.dll are a common target because they are used by multiple programs and games. Infections might remove the file completely, force it to function differently, or damage it so programs can’t load it properly, causing the not found error.

Malware also targets the Windows Registry and can make it think the DLL is missing when it still exists.

Accidental Deletion – When a program or game needs to use MFReadWrite.dll, it can accidentally delete the file if installation, updates, or uninstallation goes wrong. Some badly coded software might delete the file when you uninstall it even though it’s a shared file.

Missing Media Feature Pack – MFReadWrite.dll is part of Microsoft’s Media Feature pack. If this pack was never installed, is outdated, or is corrupted itself, this can lead to MFReadWrite.dll being missing.

Corruption – Any files and other data on your computer, including MFReadWrite.dll, can be corrupted if the system shuts down unexpectedly while the file is in memory. This can happen due to power surges, hardware failure, or accidentally pulling the power cable.

False Antivirus Alert – If a new program calls the MFReadWrite.dll file or tries to update it, some overactive antivirus software will quarantine the file, making it inaccessible or ‘missing’. This is because it thinks the software is trying to modify Windows without authorization.

How to fix MFReadWrite.dll missing errors on Windows 11?

When I first got the MFReadWrite.dll missing error, I was able to fix it by downloading the latest Windows Media Feature Pack, which comes bundled with the DLL file. However, when it occurred again with no clear cause, I turned to Fortect’s DLL fixer to find and replace the file automatically.

The ideal solution for you depends on the underlying cause, but after researching the problem deeply, these steps and solutions can apply to all errors:

Note: Before performing a fix, it’s a good idea to check Windows update and to scan for malware, so you know your system is in a secure condition.

1. Find MFReadWrite.dll Online

Before trying to replace MFReadWrite.dll, it’s important to check if it actually exists in the C:\Windows\System32 and C:\Windows\SysWOW64 folders.

If you find it, the file may be corrupted, or there could be a deeper problem with the Windows Registry. If you can’t find the file, then you can try the following methods to replace it:

1. Go to Google or your favorite search engine and search for: Download MFReadWrite.dll for Windows 11.

2. Always check reviews before downloading a DLL file from a random site, because not all are legitimate. All you need is MFReadWrite.dll, so ignore anything else that’s zipped or bundled with the download.

3. Place MFReadWrite.dll in the C:\Windows\System32 and C:\Windows\SysWOW64 folders.

4. Reopen the program that first displayed the not found error to see if it’s fixed.

5. If not, you can try registering the DLL using the Windows command prompt:

6. Use the Windows start menu search bar and type CMD.

7. Before opening the Command Prompt click run as administrator on the right.

8. Use the cd command for the folder path like this and press enter:

cd C:\Windows\System32 or cd C:\Windows\SysWOW64

9. Enter the regsvr32 command with the MFReadWrite.dll file name, and press enter:

regsvr32 MFReadWrite.dll

10. A message confirming the registration should appear.

2. Reinstall the Program

Many MFReadWrite.dll missing error messages suggest reinstalling the program that displays the error. This is because the software may come bundled with the DLL file and put it back in the correct folder.

If an update or installation was interrupted, this is a quick way to solve the problem.

However, because MFReadWrite.dll is a core Windows DLL shared among many programs, most new software assumes the file is already on the system and does not bundle it with the installer. If reinstalling the program doesn’t work, try these other fixes.

3. Reinstall Media Feature Pack

The Media Feature Pack is a set of codecs, DLLs, and other components that come with many versions of Windows 11 to support Windows Media Player, video editing, and other multimedia tasks. However, some regions do not include the pack by default, and it can become corrupted during Windows updates.

A good way to replace a damaged or missing MFReadWrite.dll file is to reinstall the pack or get the latest version from Microsoft.

4. Check System Files and Restore Health

On Windows 11, the System File Checker (SFC) is a built-in command-line utility that allows you to scan, and repair corrupted or missing system files, such as DLLs. Here’s what to do:

1. Press the Windows key, type CMD in the search bar, and run the Command Prompt as administrator.

2. When the window opens, type the following command:

sfc /scannow

3. The SFC tool will begin scanning your system. It will display its progress as it checks and repairs system files. Restart your PC when prompted.

4. After the restart, open the command prompt again and enter this command:

DISM /Online /Cleanup-Image /Restorehealth

DISM repairs and restores the integrity of your system image. This can help fix issues related to system corruption.

5. Restart your PC when prompted.

5. Use a Restore Point

Using a restore point on Windows 11 allows you to revert your computer’s system files and settings to a previous state when the system was working correctly.

1. Press the Windows key and type Create a restore point to find the utility.

2. Click the Open System Restore button to open the System Restoration Wizard.

3. Select a date from before the missing DLL error started happening.

4.Review the details of the selected restore point, making sure it’s the one you want to use. Click the Finish button to confirm your choice. Your PC will automatically restart upon completion.
