Working with Office 2007 (Open XML File Format) in earlier versions of Office for Windows and Mac
If you have Microsoft Office 2003 for Windows or Office 2004 for Mac, or if you don’t have Microsoft Office at all, there are a number of options available for working with documents created in Office 2007 for Windows or Office 2008 for Mac (for example, .pptx, .docx, .xlsx files).
For Windows users:
1. If you have Office 2003, download and install the free Office 2007 Compatibility Pack which will allow you to view and edit documents created in the newer format. Some features and formatting will not be available, such as SmartArt in PowerPoint 2007.
2. Download and install the appropriate free viewer, such as PowerPoint 2007 Viewer for Windows for viewing and printing PowerPoint 2007 files. Similar viewers exist for Word and Excel.
For Mac Users that have Microsoft PowerPoint 2003 for Mac, download and install the free OpenXML Document converter. There are unfortunately no free viewers from Microsoft for Mac computers.
