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