WinWord.exe Application Error, The application was unable to start

The application was unable to start correctly (0xc0000715). Click OK to close the application. Microsoft Word is one of the most used text editors. The executable file name for the application is WinWord.exe. Many users have reported that while trying to open the application, they get the following error:



The Application Was Unable To Start Correctly (0xc0000715). Click Ok To Close The Application.


The issue also occurs with Microsoft Outlook if Microsoft Word files are attached to the emails in its profile. Microsoft launched an update to fix the problem, however, it won’t work if the .dll files associated with the suite are already corrupt.


The causes behind the issue are as follows:

1] Problems with the user profile.

2] The office suite has gone corrupt.

3] Some third party anti-virus software could be interfering with the process.

4] Malware or virus in the system.

5] Missing files in the Microsoft Office suite.

  1. Only “killing the WinWord.exe task” allows me to run it again.
    None of the other solutions work (quick repair, full repair, full reinstall, updates, antivirus off, etc)

    What is the PERMANENT solution? I can’t continue to kill every run, just to be able to ever use Word again.
