Compatibility Pack for Microsoft Office Editor's Review

With the introduction of MS Office 2007, Microsoft made some changes to its file formats. These changes improved reliability and reduce file size, but they also created some problems. If a document, workbook or presentation was created using the 2007 edition of an MS Office program (such as Word, Excel, and PowerPoint) an older version of the same program may not be able to open it. This compatibility pack brings everything into line, giving older versions the tools they need to handle material produced with the newer versions. This lets you browse, edit and save all your new documents no matter what version of MS Office you're currently using. 

Pros: Allows earlier versions of Word, Excel, and PowerPoint to read MS Office 2007 files.

Cons: None.

Conclusion: This handy free download will let you fix compatibility issues between various different versions of Microsoft Office.
