How to Fix FFMPEG.dll is Missing

The FFMPEG.dll is missing error occurs when there is a corruption in system files and the system can not find this DLL file. This may also happen when an application is not being installed properly.

Sometimes, the error dialog box says “FFMPEG.dll is missing” appears when a user attempts to set up an application. It also appears when a user turns on the computer or accesses some websites. These are some applications on which the error is primarily reported:

  • Format Factory
  • Skype
  • Teams
  • Deezer for Windows
  • WhatsApp for Windows
  • Discord
  • Vortex for Windows
  • G Hub
  • MTZ Client
  • Sia-U

Keep in mind that your system drivers are all updated and no background application is running by going to Task Manager to close the operating apps. Now power off your computer and wait for a minute to power on. When your computer is ready, re-run the setup of the application that possibly caused the problem then check if the problem is solved. In addition, notice if there is anything left from the previous installations that can cause the error (You can also use uninstallers or cleaners from a 3rd-party provider)

How to Fix FFMPEG.dll is Missing in Windows 10/8/7

Method 1: Perform a System File Checker (SFC) Scan

If the error occurs because some essential files are missing or corrupted, you need to use the Windows built-in SFC tool to perform a scan. This may fix the error.

1. Run System File Checker SFC Scan using SFC Tool. To do that, open the Command Prompt as Administrator, type “sfc /scannow” and press Enter.

2. Repeat the process that caused the error and check again if the error is fixed.

Method 2: Copy the Folder into the Installation directory of the Application

When you reinstall an application without removing leftovers from the older installation, you accidentally create a duplication of application files. When this happens, you can try to copy all the new files and paste them to the previous folder. For example, we will do this to Microsoft Teams but in some cases, you have to try harder to work it out.

1. First, stop any Microsoft Teams operations in the Task Manager.

2. Press Windows+R to open the Run dialog box, and execute the following:


3. Navigate to Microsoft folder and find Teams folder.

4. If there is more than one folder starting from Current current and current-s1, copy all the contents from other folders (current-s1 folder) to the folder with default name (current folder). Ignore all the notifications and reboot the computer after the progress.

5. After rebooting, check if the error is fixed.

Solution 3: Clear the Cache of the Problematic Application

The cache is used to improve performance and enhance user experience. However, if the cache files of an application are broken, the error will occur. In this case, removing cache files may be the solution. For example, we will do this to Microsoft Teams but in some cases, you have to try harder to work it out.

1. Run no process and stop any Microsoft Teams operations in the Task Manager then open the Run dialog box by pressing Windows+R.

2. Follow each of the paths below and delete all files there (Execute Teams if it shows up):

3. Reboot your PC after deleting all files and check if the error is fixed.

4. If the error still appears, repeat step 1 and launch the Run dialog box then execute this command:






%appdata%\Microsoft\teams\Local Storage


5. Right-click on the Teams folder and choose Delete.

6. Confirm to put it in the Recycle Bin and restart your computer.

Check if the error is fixed after restarting.

Solution 4: Reinstall the Problematic Application

The FFMPEG.dll missing error may appear when you last installed the program incorrectly or the newest installer is not working. In this situation, you can try setting up the program again using a new installer. For example, we will do this to Microsoft Teams but in some cases, you have to try harder to work it out.

Method 5: Create a New User Account

Sometimes, there is something wrong with the user account. This can also cause the issue. In this case, signing up for a new user account to sign in may be the solution.

1. Create another system user account (be sure to set up with administrator privileges)

2. Restart your PC then log in to the system with the newly created account after restarting.

3. Check if the problem is resolved.

If the error still appears, you may try restoring the system to a previous time or reinstalling the codecs. Another way is copying the dll file from another source such as PC or Windows installer (this may import harmful things like viruses, trojan, etc.). Paste the file to its correct directory. For example, this is the directory for Microsoft Teams to paste the dll file.

If your system is a 64-bit system, paste the chosen file to the relevant 64-bit folder.
