What are sqlncli_keyfile.dll Error Messages?

Dynamic Link Library sqlncli_keyfile.dll Errors

sqlncli_keyfile.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like sqlncli_keyfile.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. Microsoft SQL Server 2008 Express (64-bit)) could share the same sqlncli_keyfile.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 sqlncli_keyfile.dll is attempted to be loaded either when Microsoft SQL Server 2008 Express (64-bit) is starting up, or in some cases already running. Some of the most common sqlncli_keyfile.dll errors include:

Access Violation at address - sqlncli_keyfile.dll.
sqlncli_keyfile.dll could not be found.
Cannot find C:\Program Files\Microsoft SQL Server\100\KeyFile\1033\sqlncli_keyfile.dll.
Cannot register sqlncli_keyfile.dll.
Cannot start Microsoft SQL Server 2008 Express (64-bit). A required component is missing: sqlncli_keyfile.dll. Please install Microsoft SQL Server 2008 Express (64-bit) again.
Failed to load sqlncli_keyfile.dll.
The application has failed to start because sqlncli_keyfile.dll was not found.
The file sqlncli_keyfile.dll is missing or corrupt.
This application failed to start because sqlncli_keyfile.dll was not found. Re-installing the application may fix this problem.

Your sqlncli_keyfile.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft SQL Server 2008 Express (64-bit)), or deleted by a malware infection. Furthermore, sqlncli_keyfile.dll file corruption could be caused from a power outage when loading Microsoft SQL Server 2008 Express (64-bit), system crash while loading sqlncli_keyfile.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.

Download sqlncli_keyfile.dll Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying sqlncli_keyfile.dll to your appropriate Windows system directory. Microsoft typically does not release Microsoft SQL Server 2008 Express (64-bit) DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing sqlncli_keyfile.dll and all other DLL files for Microsoft SQL Server 2008 Express (64-bit). An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
