How do I open a docx email attachment?

Q: How do I open a docx attachment? It looks like a Word document, but I can’t open it.


I have Microsoft Office 2003 on my computer. But if i try to open a docx attachment, I get this error message:

This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel.

A: Your friend has Office 2007  or 2010, and has sent you the document in docx format, which earlier versions of Word cannot open

You can download and install a converter to which enables earlier versions of Word to open docx files.

This converter is the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. The compatibility pack works with Office 2000, Office XP and Office 2003, and will enable you to open documents created in Office 2007 or 2010

Download Here

NB : Users of the Microsoft Office XP and 2003 programs Word, Excel, or PowerPoint—should install all High-Priority updates from Microsoft Update before downloading the Compatibility Pack.

Note that if your friend has created the document on a Mac, the converter will enable you to open docx documents created on a Mac.

Attachments of docx documents created on a Mac will often come with an extra bit of information – the “ATT0000…htm” part can be disregarded.



If you have a Mac and can’t open docx documents – you need the Open XML File Format Converter for Mac

Open XML Converter allows you to convert Open XML files that were created in Office 2008 for Mac or Office 2007 for Windows so that you can open, edit, and save them in earlier versions of Office for Mac. Open XML Converter can convert Word documents, Excel workbooks, and PowerPoint presentations that are in the Open XML Format so that you can open and edit the files in Office 2004 for Mac and Office v. X for Mac. You can choose to convert and open one file, or convert a large number of files.

      If you have Office 2007 or 2010 it sounds like the file association is broken – it needs to be re-established.

      Try the solution in this article

      “These problems occur when the association between the file and the corresponding application is missing.”
