2007 Microsoft Office Compatibility
Have you received a word document that you couldn’t open lately? Most likely you have an older version of Microsoft Office and you can’t read the new 2007 Microsoft Office edition.
As a recipient of the file, you really have two options. Either upgrade to the latest version of Microsoft Word or download the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. It’s free! Once you install this patch, you will be able to read the last version.
If you are sending a Word Document from the 2007 Office, you have the option of saving it as a different version. Most people don’t know that you can save it as a prior version.
