QTUIPanelControl.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like QTUIPanelControl.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like wuauclt.exe - to follow. These files were created so that multiple programs (eg. Apple QuickTime Player) could share the same QTUIPanelControl.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 QTUIPanelControl.dll is attempted to be loaded either when Apple QuickTime Player is starting up, or in some cases already running. Some of the most common QTUIPanelControl.dll errors include:
- Access Violation at address - QTUIPanelControl.dll.
- QTUIPanelControl.dll could not be found.
- Cannot find C:\Program Files (x86)\QuickTime\QTUIPanelControl.dll.
- Cannot register QTUIPanelControl.dll.
- Cannot start Apple QuickTime Player. A required component is missing: QTUIPanelControl.dll. Please install Apple QuickTime Player again.
- Failed to load QTUIPanelControl.dll.
- The application has failed to start because QTUIPanelControl.dll was not found.
- The file QTUIPanelControl.dll is missing or corrupt.
- This application failed to start because QTUIPanelControl.dll was not found. Re-installing the application may fix this problem.
Your QTUIPanelControl.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Apple QuickTime Player), or deleted by a malware infection. Furthermore, QTUIPanelControl.dll file corruption could be caused from a power outage when loading Apple QuickTime Player, system crash while loading QTUIPanelControl.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.
