What are L3CODECX.AX Error Messages?


Dynamic Link Library L3CODECX.AX Errors

L3CODECX.AX is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like L3CODECX.AX, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like OneDriveSetup.exe - to follow. These files were created so that multiple programs (eg. VSDC Free Video Editor) could share the same L3CODECX.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 L3CODECX.AX is attempted to be loaded either when VSDC Free Video Editor is starting up, or in some cases already running. Some of the most common L3CODECX.AX errors include:

Your L3CODECX.AX file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with VSDC Free Video Editor), or deleted by a malware infection. Furthermore, L3CODECX.AX file corruption could be caused from a power outage when loading VSDC Free Video Editor, system crash while loading L3CODECX.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 L3CODECX.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 L3CODECX.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 L3CODECX.AX error, please proceed to the Step 2 below.

Step 2: If recently installed VSDC Free Video Editor (or related software), uninstall then try reinstalling VSDC Free Video Editor software.

You can uninstall VSDC Free Video Editor software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for VSDC Free Video Editor 6.3.1.939 and click "Uninstall"

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 L3CODECX.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 L3CODECX.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 L3CODECX.AX File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate L3CODECX.AX file version. We maintain a comprehensive database of 100% malware-free L3CODECX.AX files for every applicable version of VSDC Free Video Editor. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download L3CODECX.AX Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate VSDC Free Video Editor folder location:
    Windows 10: C:\Windows\System32\
  4. 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 L3CODECX.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 L3CODECX.AX Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying L3CODECX.AX to your appropriate Windows system directory. Flash-Integro LLC typically does not release VSDC Free Video Editor 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 L3CODECX.AX and all other AX files for VSDC Free Video Editor. An incorrectly installed AX file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
