Hi,
Based on the error message, this behavior occurs because an add-in in one of the startup folders is not compatible with Word. Please try the workaround:
To identify the add-in that may be causing the behavior, follow these steps:
- Quit all Microsoft Office programs, including Word and Microsoft Outlook.
- Open the following folder for depending on your version of Word.
For Microsoft Office Word 2013:
Program Files\Microsoft Office\Office15\Startup
- Move any files that are located in that folder to your desktop.
- Open the following folder:
Documents and Settings\<var class="sbody-var">username</var>\Application Data\Microsoft\Word\Startup
- Move any files that are located in that folder to your desktop.
- Restart Word.
