pdfmonnt.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like pdfmonnt.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. Excel to PDF Converter) could share the same pdfmonnt.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 pdfmonnt.dll is attempted to be loaded either when Excel to PDF Converter is starting up, or in some cases already running. Some of the most common pdfmonnt.dll errors include:
- Access Violation at address - pdfmonnt.dll.
- pdfmonnt.dll could not be found.
- Cannot find C:\Windows\SysWOW64\pdfmonnt.dll.
- Cannot register pdfmonnt.dll.
- Cannot start Excel to PDF Converter. A required component is missing: pdfmonnt.dll. Please install Excel to PDF Converter again.
- Failed to load pdfmonnt.dll.
- The application has failed to start because pdfmonnt.dll was not found.
- The file pdfmonnt.dll is missing or corrupt.
- This application failed to start because pdfmonnt.dll was not found. Re-installing the application may fix this problem.
Your pdfmonnt.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Excel to PDF Converter), or deleted by a malware infection. Furthermore, pdfmonnt.dll file corruption could be caused from a power outage when loading Excel to PDF Converter, system crash while loading pdfmonnt.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.
