Will a Microsoft PowerPoint 2007 work on a computer that only has Microsoft PowerPoint 2003?
No, you will need to covert it first (on the computer wih 2007):1. Make sure you do not have the PowerPoint open that you wish to convert and that your work is saved.2. Rename the PowerPoint from "---.pptx" to "---.ppt".This should have converted it and should now be viewable on computers without PowerPoint 2007 or the PowerPoint 2007 Viewer.
