libpng15-15.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libpng15-15.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. SureThing CD Labeler Deluxe Edition) could share the same libpng15-15.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 libpng15-15.dll is attempted to be loaded either when SureThing CD Labeler Deluxe Edition is starting up, or in some cases already running. Some of the most common libpng15-15.dll errors include:
- Access Violation at address - libpng15-15.dll.
- libpng15-15.dll could not be found.
- Cannot find C:\Program Files (x86)\SureThing Disc Labeler 6\svg\libpng15-15.dll.

Your libpng15-15.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with SureThing CD Labeler Deluxe Edition), or deleted by a malware infection. Furthermore, libpng15-15.dll file corruption could be caused from a power outage when loading SureThing CD Labeler Deluxe Edition, system crash while loading libpng15-15.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.
