jitv.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like jitv.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. Microsoft Project Professional 2016 (64-Bit)) could share the same jitv.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 jitv.dll is attempted to be loaded either when Microsoft Project Professional 2016 (64-Bit) is starting up, or in some cases already running. Some of the most common jitv.dll errors include:
- Access Violation at address - jitv.dll.
- jitv.dll could not be found.
- Cannot find C:\Program Files (x86)\Microsoft Office\root\vfs\ProgramFilesX64\Microsoft Office\Office16\jitv.dll.
- Cannot register jitv.dll.
- Cannot start Microsoft Project Professional 2016 (64-Bit). A required component is missing: jitv.dll. Please install Microsoft Project Professional 2016 (64-Bit) again.
- Failed to load jitv.dll.
- The application has failed to start because jitv.dll was not found.
- The file jitv.dll is missing or corrupt.
- This application failed to start because jitv.dll was not found. Re-installing the application may fix this problem.
Your jitv.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Project Professional 2016 (64-Bit)), or deleted by a malware infection. Furthermore, jitv.dll file corruption could be caused from a power outage when loading Microsoft Project Professional 2016 (64-Bit), system crash while loading jitv.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.
