  • MSN Error Code 80040154


    MSN Messenger (now called Windows Live Messenger) is the Microsoft instant messaging program that is deployed with all versions of the Microsoft Windows Operating System (OS). The application is also installed on the Xbox 360, the Blackberry OS, the Zune HD, and the Symbian OS 9.x. The program connects the user to the Microsoft .NET messaging service and was first developed in the late 1990s. At the end of the 2000s, there were more than 300 million users of the service. Unfortunately, with the regular Windows OS updates that occur, the MSXML library can become corrupted. This results in MSN error code 80040154, which requires troubleshooting in order to restore MSN Messenger to an operational condition. This error is primarily experienced on Windows Vista and Windows XP, but rarely on Windows 7 OS.

      Use Long Path Tool, Long Path Tool can simplify and probably end your
      problems in unlocking, managing and renaming files that appear to have a
      long filename.
