AddintoolsOfficeMenu.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AddintoolsOfficeMenu.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AppInstaller.exe - to follow. These files were created so that multiple programs (eg. Classic Menu for Office 2007) could share the same AddintoolsOfficeMenu.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 AddintoolsOfficeMenu.dll is attempted to be loaded either when Classic Menu for Office 2007 is starting up, or in some cases already running. Some of the most common AddintoolsOfficeMenu.dll errors include:
- Access Violation at address - AddintoolsOfficeMenu.dll.
- AddintoolsOfficeMenu.dll could not be found.
- Cannot find C:\Program Files (x86)\Classic Menu for Office\AddintoolsOfficeMenu.dll.
- Cannot register AddintoolsOfficeMenu.dll.
- Cannot start Classic Menu for Office 2007. A required component is missing: AddintoolsOfficeMenu.dll. Please install Classic Menu for Office 2007 again.

- The application has failed to start because AddintoolsOfficeMenu.dll was not found.
- The file AddintoolsOfficeMenu.dll is missing or corrupt.
- This application failed to start because AddintoolsOfficeMenu.dll was not found. Re-installing the application may fix this problem.
Your AddintoolsOfficeMenu.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Classic Menu for Office 2007), or deleted by a malware infection. Furthermore, AddintoolsOfficeMenu.dll file corruption could be caused from a power outage when loading Classic Menu for Office 2007, system crash while loading AddintoolsOfficeMenu.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.
