SFSS_APO.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like SFSS_APO.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 0009-64bit_Win7_Win8_Win81_Win10_R282.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 SFSS_APO.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 SFSS_APO.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 SFSS_APO.dll errors include:
- Access Violation at address - SFSS_APO.dll.
- SFSS_APO.dll could not be found.
- Cannot find C:\Windows\System32\DriverStore\FileRepository\hdxrt.inf_amd64_b0026a592e9b4de4\SFSS_APO.dll.
- Cannot register SFSS_APO.dll.
- Cannot start Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit). A required component is missing: SFSS_APO.dll. Please install Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) again.
- Failed to load SFSS_APO.dll.
- The application has failed to start because SFSS_APO.dll was not found.
- The file SFSS_APO.dll is missing or corrupt.
- This application failed to start because SFSS_APO.dll was not found. Re-installing the application may fix this problem.
Your SFSS_APO.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, SFSS_APO.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 SFSS_APO.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.
