What are D3D9Core.dll Error Messages?


Dynamic Link Library D3D9Core.dll Errors

D3D9Core.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like D3D9Core.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Movavi Video Converter 2020) could share the same D3D9Core.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 D3D9Core.dll is attempted to be loaded either when Movavi Video Converter 2020 is starting up, or in some cases already running. Some of the most common D3D9Core.dll errors include:

Your D3D9Core.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Movavi Video Converter 2020), or deleted by a malware infection. Furthermore, D3D9Core.dll file corruption could be caused from a power outage when loading Movavi Video Converter 2020, system crash while loading D3D9Core.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 D3D9Core.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 D3D9Core.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.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button

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 D3D9Core.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  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 D3D9Core.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 D3D9Core.dll File (Caution: Advanced)

Download D3D9Core.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying D3D9Core.dll to your appropriate Windows system directory. Movavi typically does not release Movavi Video Converter 2020 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 D3D9Core.dll and all other DLL files for Movavi Video Converter 2020. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
