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