What are CLLine21.ax Error Messages?

Dynamic Link Library CLLine21.ax Errors

CLLine21.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like CLLine21.ax, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. CyberLink Media Suite) could share the same CLLine21.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 CLLine21.ax is attempted to be loaded either when CyberLink Media Suite is starting up, or in some cases already running. Some of the most common CLLine21.ax errors include:

Access Violation at address - CLLine21.ax.
CLLine21.ax could not be found.
Cannot find C:\Program Files (x86)\CyberLink\PowerDVD18\Common\VideoFilter\CLLine21.ax.
Cannot register CLLine21.ax.
Cannot start CyberLink Media Suite. A required component is missing: CLLine21.ax. Please install CyberLink Media Suite again.
Failed to load CLLine21.ax.
The application has failed to start because CLLine21.ax was not found.
The file CLLine21.ax is missing or corrupt.
This application failed to start because CLLine21.ax was not found. Re-installing the application may fix this problem.

Your CLLine21.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with CyberLink Media Suite), or deleted by a malware infection. Furthermore, CLLine21.ax file corruption could be caused from a power outage when loading CyberLink Media Suite, system crash while loading CLLine21.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 CLLine21.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 CLLine21.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 CLLine21.ax error, please proceed to the Step 2 below.

Step 2: If recently installed CyberLink Media Suite (or related software), uninstall then try reinstalling CyberLink Media Suite software.

You can uninstall CyberLink Media Suite 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"

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 CLLine21.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 CLLine21.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 CLLine21.ax File (Caution: Advanced)

We maintain a comprehensive database of 100% malware-free CLLine21.ax files for every applicable version of CyberLink Media Suite. Please follow the steps below to download and properly replace you file:

Copy this file to the appropriate CyberLink Media Suite folder location:

Windows 10: C:\Program Files\CyberLink\PowerDVD19\ShareModule32\Common\VideoFilter\
Windows 10: C:\Program Files (x86)\CyberLink\PowerDVD18\Common\VideoFilter\
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 CLLine21.ax problems.

If you are not currently backing up your data, you need to do so immediately.

Download CLLine21.ax Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying CLLine21.ax to your appropriate Windows system directory. CyberLink typically does not release CyberLink Media Suite 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 CLLine21.ax and all other AX files for CyberLink Media Suite. An incorrectly installed AX file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
