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