Office 2007 & 2010 Document Converter
Problems opening a Microsoft Office 2007 or 2010 document on a computer with another version of office?

With Office 2007 and 2010, Microsoft introduced a new file format called docx. If you receive a document with this extension but do not have Office 2007 or 2010, you will not be able to open that document. Microsoft has released a compatibility pack for Windows which can be found here.

Mac users can download the converter here.
