What are custom.xml Error Messages?


General custom.xml Runtime Errors

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

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files (x86)\Wireshark\diameter\custom.xml

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


Most XML errors are due to missing or corrupt files. Your custom.xml file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Wireshark), or deleted by a malware infection. Furthermore, custom.xml file corruption could be caused from a power outage when loading Wireshark, system crash while loading or saving custom.xml, 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 custom.xml 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 custom.xml 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 custom.xml error, please proceed to the Step 2 below.

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

You can uninstall Wireshark 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 Wireshark 3.0.0 and click "Uninstall"
  5. Follow the prompts for uninstallation.

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 custom.xml 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 custom.xml 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 custom.xml 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 custom.xml file version. We maintain a comprehensive database of 100% malware-free custom.xml files for every applicable version of Wireshark. 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 custom.xml Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate Wireshark folder location:
    Windows 10: C:\Program Files (x86)\Wireshark\diameter\
    Windows 10: C:\Program Files\MATLAB\R2019b\resources\MATLAB\zh_CN\bigdata\
    Windows 10: C:\Program Files\MATLAB\R2019b\resources\MATLAB\ko_KR\bigdata\
    Windows 10: C:\Program Files\MATLAB\R2019b\resources\MATLAB\ja_JP\bigdata\
    Windows 10: C:\Program Files\MATLAB\R2019b\resources\MATLAB\en\bigdata\
  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 custom.xml 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 custom.xml Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying custom.xml to your appropriate Windows system directory. The Wireshark Team typically does not release Wireshark XML 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 custom.xml and all other XML files for Wireshark. An incorrectly installed XML file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
