What are LAVVideo.ax Error Messages?


Dynamic Link Library LAVVideo.ax Errors

LAVVideo.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like LAVVideo.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 8 Codecs Pack) could share the same LAVVideo.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 LAVVideo.ax is attempted to be loaded either when Windows 8 Codecs Pack is starting up, or in some cases already running. Some of the most common LAVVideo.ax errors include:

Your LAVVideo.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows 8 Codecs Pack), or deleted by a malware infection. Furthermore, LAVVideo.ax file corruption could be caused from a power outage when loading Windows 8 Codecs Pack, system crash while loading LAVVideo.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 LAVVideo.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 LAVVideo.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):

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

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

Step 2: If recently installed Windows 8 Codecs Pack (or related software), uninstall then try reinstalling Windows 8 Codecs Pack software.

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

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 LAVVideo.ax error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

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

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