What are core.sdf Error Messages?


General core.sdf Runtime Errors

core.sdf file errors often occur during the startup phase of CMS, but can also occur while the program is running. These types SDF errors are also known as “runtime errors” because they occur while CMS is running. Here are some of the most common core.sdf runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files (x86)\NovoSun Technology Limited\Security Camera Suite\CyeWeb\Core\core.sdf

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most SDF errors are due to missing or corrupt files. Your core.sdf file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with CMS), or deleted by a malware infection. Furthermore, core.sdf file corruption could be caused from a power outage when loading CMS, system crash while loading or saving core.sdf, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix core.sdf 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 core.sdf issue. These troubleshooting steps are listed in the recommended order of execution.

If Those Steps Fail: Download and Replace Your core.sdf File (Caution: Advanced)

We maintain a comprehensive database of 100% malware-free core.sdf files for every applicable version of CMS. Please follow the steps below to download and properly replace you file:

  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate CMS folder location:
    Windows 10: C:\Program Files (x86)\NovoSun Technology Limited\Security Camera Suite\CyeWeb\Core\
    Windows 10: C:\ProgramData\NovoSun\CyeWeb\Common\
  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve core.sdf problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download core.sdf Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying core.sdf to your appropriate Windows system directory. NovoSun Technology typically does not release CMS SDF 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 core.sdf and all other SDF files for CMS. An incorrectly installed SDF file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
