What are QtSql4.dll Error Messages?


Dynamic Link Library QtSql4.dll Errors

QtSql4.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like QtSql4.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like FileCoAuth.exe - to follow. These files were created so that multiple programs (eg. MediaFire) could share the same QtSql4.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 QtSql4.dll is attempted to be loaded either when MediaFire is starting up, or in some cases already running. Some of the most common QtSql4.dll errors include:

Your QtSql4.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MediaFire), or deleted by a malware infection. Furthermore, QtSql4.dll file corruption could be caused from a power outage when loading MediaFire, system crash while loading QtSql4.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 QtSql4.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 QtSql4.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 QtSql4.dll error, please proceed to the Step 2 below.

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

You can uninstall MediaFire software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for MediaFire 1.8.12.11026 and click "Uninstall"

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 QtSql4.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 QtSql4.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 QtSql4.dll File (Caution: Advanced)

    Windows 10: C:\Program Files\DAZ 3D\DAZStudio4\
    Windows 10: C:\Program Files (x86)\Nokia\Nokia PC Suite 7\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve QtSql4.dll problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download QtSql4.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying QtSql4.dll to your appropriate Windows system directory. MediaFire typically does not release MediaFire 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 QtSql4.dll and all other DLL files for MediaFire. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
