key4.db file errors often occur during the startup phase of Mozilla Thunderbird, but can also occur while the program is running. These types DB errors are also known as “runtime errors” because they occur while Mozilla Thunderbird is running. Here are some of the most common key4.db runtime errors:
Runtime Error!
Program: C:\Users\Tester\AppData\Roaming\Thunderbird\Profiles\huaunoht.default-release\key4.db
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
Most DB errors are due to missing or corrupt files. Your key4.db file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Mozilla Thunderbird), or deleted by a malware infection. Furthermore, key4.db file corruption could be caused from a power outage when loading Mozilla Thunderbird, system crash while loading or saving key4.db, 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.

If Windows Update failed to resolve the key4.db error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
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 key4.db file version. We maintain a comprehensive database of 100% malware-free key4.db files for every applicable version of Mozilla Thunderbird. Please follow the steps below to download and properly replace you file:
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 key4.db 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.
CAUTION : We strongly advise against downloading and copying key4.db to your appropriate Windows system directory. Mozilla typically does not release Mozilla Thunderbird DB 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 key4.db and all other DB files for Mozilla Thunderbird. An incorrectly installed DB file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
