What are thunderbird.exe Error Messages?


thunderbird.exe Runtime Errors

Runtime errors are Mozilla Thunderbird errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when thunderbird.exe is attempted to be loaded either when Mozilla Thunderbird is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Mozilla Thunderbird.

In most cases, thunderbird.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these thunderbird.exe error messages mean that Mozilla Thunderbird was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Mozilla Thunderbird will be unable to start without resolving these errors.

Some of the most common thunderbird.exe errors include:

  • thunderbird.exe - Bad Image.
  • thunderbird.exe Application Error.
  • thunderbird.exe could not be found.
  • thunderbird.exe could not be installed.
  • thunderbird.exe could not be launched. Class not registered.
  • thunderbird.exe could not be started.
  • thunderbird.exe failed to initialize properly.
  • thunderbird.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
  • thunderbird.exe is not a valid Win32 application.
  • thunderbird.exe is not running.
  • Cannot find thunderbird.exe.
  • Error starting program: thunderbird.exe.
  • Faulting Application Path: thunderbird.exe.
  • The file thunderbird.exe is missing or corrupt.

System Error


The program can’t start because thunderbird.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the thunderbird.exe error is key to properly resolving these errors. Although most of these EXE errors affecting thunderbird.exe will happen during startup, occasionally you will encounter a runtime error while using Thunderbird. This can occur due to poor programming on behalf of Mozilla Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of thunderbird.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
