7za64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like 7za64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like onenoteim.exe - to follow. These files were created so that multiple programs (eg. Comodo Internet Security) could share the same 7za64.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 7za64.dll is attempted to be loaded either when Comodo Internet Security is starting up, or in some cases already running. Some of the most common 7za64.dll errors include:
- Access Violation at address - 7za64.dll.
- 7za64.dll could not be found.
- Cannot find C:\Program Files (x86)\Comodo\COMODO Secure Shopping\7za64.dll.
- Cannot register 7za64.dll.
- Cannot start Comodo Internet Security. A required component is missing: 7za64.dll. Please install Comodo Internet Security again.
- Failed to load 7za64.dll.
- The application has failed to start because 7za64.dll was not found.
- The file 7za64.dll is missing or corrupt.
- This application failed to start because 7za64.dll was not found. Re-installing the application may fix this problem.
Your 7za64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Comodo Internet Security), or deleted by a malware infection. Furthermore, 7za64.dll file corruption could be caused from a power outage when loading Comodo Internet Security, system crash while loading 7za64.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.
