What are libpng13.dll Error Messages?

Dynamic Link Library libpng13.dll Errors

libpng13.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libpng13.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. 123 PDF Converter) could share the same libpng13.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 libpng13.dll is attempted to be loaded either when 123 PDF Converter is starting up, or in some cases already running. Some of the most common libpng13.dll errors include:

Access Violation at address - libpng13.dll.
libpng13.dll could not be found.
Cannot find C:\ProgramData\PCOCRTemp\libpng13.dll.
Cannot register libpng13.dll.
Cannot start 123 PDF Converter. A required component is missing: libpng13.dll. Please install 123 PDF Converter again.
Failed to load libpng13.dll.
The application has failed to start because libpng13.dll was not found.
The file libpng13.dll is missing or corrupt.
This application failed to start because libpng13.dll was not found. Re-installing the application may fix this problem.

Your libpng13.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with 123 PDF Converter), or deleted by a malware infection. Furthermore, libpng13.dll file corruption could be caused from a power outage when loading 123 PDF Converter, system crash while loading libpng13.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 libpng13.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 libpng13.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.

Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the libpng13.dll error, please proceed to the Step 2 below.

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 libpng13.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
