What are DCEXEC.rll Error Messages?

Dynamic Link Library DCEXEC.rll Errors

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

• Access Violation at address - DCEXEC.rll.
• DCEXEC.rll could not be found.
• Cannot find C:\Program Files (x86)\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Binn\Resources\1033\DCEXEC.rll.
• Cannot register DCEXEC.rll.
• Cannot start Microsoft SQL Server. A required component is missing: DCEXEC.rll. Please install Microsoft SQL Server again.
• Failed to load DCEXEC.rll.
• The application has failed to start because DCEXEC.rll was not found.
• The file DCEXEC.rll is missing or corrupt.
• This application failed to start because DCEXEC.rll was not found. Re-installing the application may fix this problem.

Your DCEXEC.rll 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, DCEXEC.rll file corruption could be caused from a power outage when loading Microsoft SQL Server, system crash while loading DCEXEC.rll, 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 DCEXEC.rll Errors in 3 Steps (Time to complete: ~5-15 minutes)

Microsoft Corporation

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

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

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

If Those Steps Fail: Download and Replace Your DCEXEC.rll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate DCEXEC.rll file version. We maintain a comprehensive database of 100% malware-free DCEXEC.rll files for every applicable version of Microsoft SQL Server. Please follow the steps below to download and properly replace you file:

1. Locate your Windows operating system version in the list of below "Download DCEXEC.rll Files".
2. Click the appropriate "Download Now" button and download your Windows file version.
3. Copy this file to the appropriate Microsoft SQL Server folder location:
   
   Windows 10: C:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Binn\Resources\1033\
   Windows 10: C:\Program Files (x86)\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Binn\Resources\1033\
   
4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.
