What are xulrunner.exe Error Messages?


xulrunner.exe Runtime Errors

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

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

Some of the most common xulrunner.exe errors include:

  • xulrunner.exe - Bad Image.
