What are sqlsupport_keyfile.dll Error Messages?

Dynamic Link Library sqlsupport_keyfile.dll Errors

sqlsupport_keyfile.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like sqlsupport_keyfile.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AppInstaller.exe - to follow. These files were created so that multiple programs (eg. Microsoft SQL Server) could share the same sqlsupport_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 sqlsupport_keyfile.dll is attempted to be loaded either when Microsoft SQL Server is starting up, or in some cases already running. Some of the most common sqlsupport_keyfile.dll errors include:

Access Violation at address - sqlsupport_keyfile.dll.
sqlsupport_keyfile.dll could not be found.
Cannot find C:\Program Files (x86)\Microsoft SQL Server\100\KeyFile\1033\sqlsupport_keyfile.dll.
Cannot register sqlsupport_keyfile.dll.
Cannot start Microsoft SQL Server. A required component is missing: sqlsupport_keyfile.dll. Please install Microsoft SQL Server again.
Failed to load sqlsupport_keyfile.dll.
The application has failed to start because sqlsupport_keyfile.dll was not found.
The file sqlsupport_keyfile.dll is missing or corrupt.
This application failed to start because sqlsupport_keyfile.dll was not found. Re-installing the application may fix this problem.

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

How to Fix sqlsupport_keyfile.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your sqlsupport_keyfile.dll issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the sqlsupport_keyfile.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Microsoft SQL Server (or related software), uninstall then try reinstalling Microsoft SQL Server software.

You can uninstall Microsoft SQL Server software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many sqlsupport_keyfile.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the sqlsupport_keyfile.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

Windows 10: C:\Program Files (x86)\Microsoft SQL Server\100\KeyFile\1033\

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

CAUTION : We strongly advise against downloading and copying sqlsupport_keyfile.dll to your appropriate Windows system directory. Microsoft typically does not release Microsoft SQL Server 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 sqlsupport_keyfile.dll and all other DLL files for Microsoft SQL Server. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
