What are D3DX9_42.dll Error Messages?


Dynamic Link Library D3DX9_42.dll Errors

D3DX9_42.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like D3DX9_42.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 D3DX9_42.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 D3DX9_42.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 D3DX9_42.dll errors include:

Your D3DX9_42.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, D3DX9_42.dll file corruption could be caused from a power outage when loading CyberLink Media Suite, system crash while loading D3DX9_42.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.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your D3DX9_42.dll issue. These troubleshooting steps are listed in the recommended order of execution.

  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 D3DX9_42.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

Download D3DX9_42.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying D3DX9_42.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 D3DX9_42.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.
