What are 264dmmx.dll Error Messages?

Dynamic Link Library 264dmmx.dll Errors

264dmmx.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like 264dmmx.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. CyberLink Media Suite) could share the same 264dmmx.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 264dmmx.dll is attempted to be loaded either when CyberLink Media Suite is starting up, or in some cases already running. Some of the most common 264dmmx.dll errors include:

Your 264dmmx.dll 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, 264dmmx.dll file corruption could be caused from a power outage when loading CyberLink Media Suite, system crash while loading 264dmmx.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 264dmmx.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 264dmmx.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.

  1. Hit the Windows Start button

  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 264dmmx.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 264dmmx.dll File (Caution: Advanced)

CAUTION : We strongly advise against downloading and copying 264dmmx.dll to your appropriate Windows system directory. CyberLink typically does not release CyberLink Media Suite 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 264dmmx.dll and all other DLL files for CyberLink Media Suite. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
