What are STCore.dll Error Messages?


Dynamic Link Library STCore.dll Errors

STCore.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like STCore.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 3DViewer.exe - to follow. These files were created so that multiple programs (eg. Avira Free Antivirus) could share the same STCore.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 STCore.dll is attempted to be loaded either when Avira Free Antivirus is starting up, or in some cases already running. Some of the most common STCore.dll errors include:

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

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

You can uninstall Avira Free Antivirus 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 Avira Free Antivirus 15.0.1909.1591 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 STCore.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 STCore.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
