buFScsdk.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like buFScsdk.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. Norton Security Premium) could share the same buFScsdk.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 buFScsdk.dll is attempted to be loaded either when Norton Security Premium is starting up, or in some cases already running. Some of the most common buFScsdk.dll errors include:
- Access Violation at address - buFScsdk.dll.
- buFScsdk.dll could not be found.
- Cannot find C:\Program Files (x86)\Norton Security with Backup\Engine\22.6.0.142\buFScsdk.dll.
- Cannot register buFScsdk.dll.
- Cannot start Norton Security Premium. A required component is missing: buFScsdk.dll. Please install Norton Security Premium again.
- Failed to load buFScsdk.dll.
- The application has failed to start because buFScsdk.dll was not found.
- The file buFScsdk.dll is missing or corrupt.
- This application failed to start because buFScsdk.dll was not found. Re-installing the application may fix this problem.
Your buFScsdk.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Norton Security Premium), or deleted by a malware infection. Furthermore, buFScsdk.dll file corruption could be caused from a power outage when loading Norton Security Premium, system crash while loading buFScsdk.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.
