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