What are ffdshow.ax Error Messages?

Dynamic Link Library ffdshow.ax Errors

ffdshow.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ffdshow.ax, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Windows Media Codec Pack) could share the same ffdshow.ax file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared AX file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when ffdshow.ax is attempted to be loaded either when Windows Media Codec Pack is starting up, or in some cases already running. Some of the most common ffdshow.ax errors include:

Access Violation at address - ffdshow.ax.
ffdshow.ax could not be found.
Cannot find C:\Program Files (x86)\Windows Media Codec Pack\FFDShow\ffdshow.ax.
Cannot register ffdshow.ax.
Cannot start Windows Media Codec Pack. A required component is missing: ffdshow.ax. Please install Windows Media Codec Pack again.
Failed to load ffdshow.ax.
The application has failed to start because ffdshow.ax was not found.
The file ffdshow.ax is missing or corrupt.
This application failed to start because ffdshow.ax was not found. Re-installing the application may fix this problem.

Your ffdshow.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows Media Codec Pack), or deleted by a malware infection. Furthermore, ffdshow.ax file corruption could be caused from a power outage when loading Windows Media Codec Pack, system crash while loading ffdshow.ax, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix ffdshow.ax Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your ffdshow.ax issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the ffdshow.ax error, please proceed to the Step 2 below.

Step 2: If recently installed Windows Media Codec Pack (or related software), uninstall then try reinstalling Windows Media Codec Pack software.

You can uninstall Windows Media Codec Pack software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"
Find the entry for Windows Media Codec Pack 2 and click "Uninstall"
Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall Windows Media Codec Pack software.

If this Step 2 fails as well, please proceed to the Step 3 below.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many ffdshow.ax error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the ffdshow.ax error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your ffdshow.ax File (Caution: Advanced)

We maintain a comprehensive database of 100% malware-free ffdshow.ax files for every applicable version of Windows Media Codec Pack. Please follow the steps below to download and properly replace you file:

Windows 10: C:\Program Files (x86)\Windows Media Codec Pack\FFDShow\
Windows 10: C:\Program Files (x86)\K-Lite Codec Pack\ffdshow\
Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve ffdshow.ax problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

Download ffdshow.ax Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying ffdshow.ax to your appropriate Windows system directory. Green Torch Studios typically does not release Windows Media Codec Pack AX files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing ffdshow.ax and all other AX files for Windows Media Codec Pack. An incorrectly installed AX file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
