The latest version of Office is 2007 – more people have now moved up to this version. That’s fine, but this new version of Office defaults to a different file type. For instance, documents created in Word will have the extension of .docx rather the extension we’re used to seeing, .doc
The issue this can bring up is if you are not running Office 2007, and someone sends you a document created in it with the .docx extension. Earlier versions of Office are not able to open this new file extension.
Never fear, a solution is nearby. Microsoft has available a free download called the Microsoft Office Compatability Pack – this will allow you to open and view Word, Excel, and Power Point documents prepared in Office 2007. Here is a link that will take you to the page with instructions on how to download and use.
