Issue: How to fix FFMPEG.dll is missing error in Windows?
Hello. I am running Windows 10 and get the following error when I boot up: “The code execution cannot proceed because ffmpeg.dll was not found. Reinstalling the program may fix this problem.” How do I know which program is causing the issue? Any tips would be highly appreciated.
Windows errors can be very frustrating. They can prevent people from opening apps, performing basic tasks, like copying files, and much more. Recently users have encountered the “FFMPEG.dll is missing” error that usually appears when users are trying to install an application, trying to boot up the system, or in rare cases, accessing websites like GitHub.
A DLL (Dynamic-Link Library) contains code and data that can be used by more than one program at the same time. You may see the “FFMPEG.dll is missing” error because important system files are corrupted and are causing the system directory to be unable to find this file. The error can also appear after an attempted installation that failed or a corrupt installation of an application. The issue is mainly reported on the following apps:
- Format Factory
- G Hub
- MTZ Client
In this guide, we will use Microsoft Teams as an example, so keep in mind that you first have to identify which app is causing the error. But before you proceed, you should ensure that your drivers are updated. If you are not sure how, you can read our guide “How to easily update all drivers, and why is it needed?” Secondly, close all third-party applications in Task Manager. No other processes should be running except for Windows system tasks.
