What are Fcntl.html Error Messages?


General Fcntl.html Runtime Errors

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

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files\MATLAB\R2019b\sys\perl\win32\html\lib\Fcntl.html

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


Most HTML errors are due to missing or corrupt files. Your Fcntl.html file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MATLAB), or deleted by a malware infection. Furthermore, Fcntl.html file corruption could be caused from a power outage when loading MATLAB, system crash while loading or saving Fcntl.html, 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 Fcntl.html 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 Fcntl.html 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):

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

If the Step 1 fails to resolve the Fcntl.html error, please proceed to the Step 2 below.

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

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

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for MATLAB R2009a and click "Uninstall"
  5. Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall MATLAB software.

If this Step 2 fails as well, please proceed to the Step 3 below.

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 Fcntl.html 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 Fcntl.html 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 Fcntl.html 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 Fcntl.html file version. We maintain a comprehensive database of 100% malware-free Fcntl.html files for every applicable version of MATLAB. 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 Fcntl.html Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate MATLAB folder location:
    Windows 10: C:\Program Files\MATLAB\R2019b\sys\perl\win32\html\lib\
  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.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve Fcntl.html 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 Fcntl.html Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying Fcntl.html to your appropriate Windows system directory. MathWorks typically does not release MATLAB HTML 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 Fcntl.html and all other HTML files for MATLAB. An incorrectly installed HTML file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
