What are DecoderMgr.dll Error Messages?


Dynamic Link Library DecoderMgr.dll Errors

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

Your DecoderMgr.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Wondershare UniConverter), or deleted by a malware infection. Furthermore, DecoderMgr.dll file corruption could be caused from a power outage when loading Wondershare UniConverter, system crash while loading DecoderMgr.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 DecoderMgr.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 DecoderMgr.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
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the DecoderMgr.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Wondershare UniConverter (or related software), uninstall then try reinstalling Wondershare UniConverter software.

You can uninstall Wondershare UniConverter software by following these instructions (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 DecoderMgr.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 DecoderMgr.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 DecoderMgr.dll File (Caution: Advanced)

We maintain a comprehensive database of 100% malware-free DecoderMgr.dll files for every applicable version of Wondershare UniConverter.

    Windows 10: C:\Program Files (x86)\Wondershare\Video Converter Ultimate\
    Windows 10: C:\Program Files\Wondershare\Wondershare Filmora\
    Windows 10: C:\Program Files (x86)\Wondershare\dsb_deluxe-cnet\
  4. Restart your computer.

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


CAUTION : We strongly advise against downloading and copying DecoderMgr.dll to your appropriate Windows system directory. Wondershare Software Co., Ltd. typically does not release Wondershare UniConverter DLL files for download because they are bundled together inside of a software installer.
