SFNHK64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like SFNHK64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit)) could share the same SFNHK64.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 SFNHK64.dll is attempted to be loaded either when Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) is starting up, or in some cases already running. Some of the most common SFNHK64.dll errors include:
- Access Violation at address - SFNHK64.dll.
- SFNHK64.dll could not be found.
- Cannot find C:\Windows\System32\DriverStore\FileRepository\hdxrt.inf_amd64_b0026a592e9b4de4\SFNHK64.dll.
- Cannot register SFNHK64.dll.
- Cannot start Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit). A required component is missing: SFNHK64.dll. Please install Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) again.
- Failed to load SFNHK64.dll.
- The application has failed to start because SFNHK64.dll was not found.
- The file SFNHK64.dll is missing or corrupt.
- This application failed to start because SFNHK64.dll was not found. Re-installing the application may fix this problem.
Your SFNHK64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit)), or deleted by a malware infection. Furthermore, SFNHK64.dll file corruption could be caused from a power outage when loading Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit), system crash while loading SFNHK64.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.
