What are H264VDec.dll Error Messages?

Dynamic Link Library H264VDec.dll Errors

H264VDec.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like H264VDec.dll, 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. Corel WinDVD) could share the same H264VDec.dll 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 DLL 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 H264VDec.dll is attempted to be loaded either when Corel WinDVD is starting up, or in some cases already running. Some of the most common H264VDec.dll errors include:

Access Violation at address - H264VDec.dll.
H264VDec.dll could not be found.
Cannot find C:\Program Files (x86)\Corel\WinDVD11\H264VDec.dll.
Cannot register H264VDec.dll.
Cannot start Corel WinDVD. A required component is missing: H264VDec.dll. Please install Corel WinDVD again.
Failed to load H264VDec.dll.
The application has failed to start because H264VDec.dll was not found.
The file H264VDec.dll is missing or corrupt.
This application failed to start because H264VDec.dll was not found. Re-installing the application may fix this problem.

Your H264VDec.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Corel WinDVD), or deleted by a malware infection. Furthermore, H264VDec.dll file corruption could be caused from a power outage when loading Corel WinDVD, system crash while loading H264VDec.dll, 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 H264VDec.dll 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 H264VDec.dll 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.

Follow the steps in the System Restore Wizard to choose a relevant restore point.

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 H264VDec.dll 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 H264VDec.dll 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 H264VDec.dll File (Caution: Advanced)

Windows 10: C:\Program Files\Corel\Corel VideoStudio 2019\Common Files\MPEG\
Restart your computer.

Download H264VDec.dll Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying H264VDec.dll to your appropriate Windows system directory. Corel typically does not release Corel WinDVD DLL 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 H264VDec.dll and all other DLL files for Corel WinDVD. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
