What are JetMPAx.ax Error Messages?

Dynamic Link Library JetMPAx.ax Errors

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

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

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

Step 2: If recently installed JetVideo Basic VX (or related software), uninstall then try reinstalling JetVideo Basic VX software.

You can uninstall JetVideo Basic VX 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 JetVideo Basic VX 8.1.7.20702 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 JetMPAx.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 JetMPAx.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 JetMPAx.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 JetMPAx.ax file version. We maintain a comprehensive database of 100% malware-free JetMPAx.ax files for every applicable version of JetVideo Basic VX. Please follow the steps below to download and properly replace you file:

Locate your Windows operating system version in the list of below "Download JetMPAx.ax Files".
Click the appropriate "Download Now" button and download your Windows file version.
Copy this file to the appropriate JetVideo Basic VX folder location:

Windows 10: C:\Program Files (x86)\Common Files\COWON\
Windows 10: C:\Program Files (x86)\Common Files\COWON\
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 JetMPAx.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 JetMPAx.ax Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying JetMPAx.ax to your appropriate Windows system directory. Cowon America typically does not release JetVideo Basic VX 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 JetMPAx.ax and all other AX files for JetVideo Basic VX. An incorrectly installed AX file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
