qmldbg_quickprofiler.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like qmldbg_quickprofiler.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. Viber for Windows) could share the same qmldbg_quickprofiler.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_quickprofiler.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_quickprofiler.dll errors include:
- Access Violation at address - qmldbg_quickprofiler.dll.
- qmldbg_quickprofiler.dll could not be found.
- Cannot find C:\Users\Tester\AppData\Local\Viber\qmltooling\qmldbg_quickprofiler.dll.
- Cannot register qmldbg_quickprofiler.dll.
- Cannot start Viber for Windows. A required component is missing: qmldbg_quickprofiler.dll. Please install Viber for Windows again.
- Failed to load qmldbg_quickprofiler.dll.
- The application has failed to start because qmldbg_quickprofiler.dll was not found.
- The file qmldbg_quickprofiler.dll is missing or corrupt.
- This application failed to start because qmldbg_quickprofiler.dll was not found. Re-installing the application may fix this problem.
Your qmldbg_quickprofiler.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_quickprofiler.dll file corruption could be caused from a power outage when loading Viber for Windows, system crash while loading qmldbg_quickprofiler.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.
