Opening Office 2007 files in older Office versions

If you use Microsoft Office editions 2000 through 2003 and aren't ready to upgrade, you should be able to open work that someone else saved in the new, 2007 formats. However, this process isn't seamless. First, you must take steps to allow the older software to read the newer file.

The Compatibility Pack download that makes this possible requires that you run Word, Excel and PowerPoint 2000 or 2002 with Service Pack 3 or run the 2003 editions of those applications with SP1 or higher. Your operating system must be Windows 2000 SP4, Windows Server 2003 or Windows XP with SP1 or newer.

Microsoft Office 2003 and 2000 should prompt you to download the Compatibility Pack when you try to open Office 2007's Open XML-based files.

If you're running older Office software that meets these requirements, you should receive a one-time prompt to download the Compatibility Pack when you try to open a 2007 Office file. However, without the latest software updates, the Compatibility Pack may not fully work.

If you try to open an Office 2007 file with Office 2003 or 2000 but aren't prompted to install a Compatibility Pack, then you probably need to update your older Office software first, by visiting update.microsoft.com. When that's done, you can restart your machine and get the Compatibility Pack at download.microsoft.com.

After you've installed the Compatibility Pack, you must restart your computer for the changes to take effect. With that done, you should be able to open Office 2007 files with older Office software. If you open an Office 2007 file in Office 2003, choosing Save will keep that file in the new format. The same is true for Word 2000. In Excel and PowerPoint 2000, however, you must choose Save As to keep an Office 2007 file from reverting to an earlier format.

Microsoft Office Standard 2007

Review Microsoft Office Standard 2007 is a worthy upgrade if you need to make sleeker-looking documents and presentations to share with others, and Outlook is better than ever. However, you can stick to your current software if you don't feel that it lacks anything.
Word 2007

Review If you're ready to let go of old habits from previous versions of Word and want to make sleeker-looking documents, Word 2007 is worth the upgrade. However, less expensive alternatives deliver its core features without the clutter.
Excel 2007 RTM

Preview Excel 2007's radical overhaul is attractive if you depend upon spreadsheets that can display data patterns visually with charts and conditional formatting. Plus, the new interface places formulas and other number-crunching tools within easy reach.
PowerPoint 2007

Review Microsoft PowerPoint 2007 makes prettier presentations, so an upgrade may be in order if your work is particularly image-focused and you don't mind relearning the application. If PowerPoint 2003 serves you well, however, it offers most of the same features, albeit with flatter-looking graphics.
Outlook 2007

Review If you work with Microsoft Outlook on a daily basis, this upgrade can make scheduling simpler and emailing more interesting. Still, we wish Instant Search and email rendering were better.
