Using .docx Files with Older Versions of MS Word

MerusCase merges documents into a .docx file format, which Word 2007 uses by default. However, older versions of Word cannot open, edit or save files of this format.


Luckily, Microsoft provides a Compatibility Pack for Word 2000, XP, or 2003 that provides support for these files.


To resolve the issue, you can download and install Microsoft's Office Compatibility Pack. For more information, please read this article published by Microsoft.
