When you install a newer version of Microsoft Word, Setup replaces the current versions of the Microsoft Equation Editor and Microsoft Graph with the newer versions.

If you have both an earlier version of Microsoft Word and a later version on the same computer, equations and graphs that you create in the earlier version are automatically created with the newer versions of Equation Editor and Microsoft Graph. When you try to work on these on a computer that has only the earlier version of Word, the equations and graphs cannot be edited.

Examples:

• Computer 1 has both Word 7.0 and Word 97 installed. Therefore, it uses the newest version of the Equation Editor and Microsoft Graph available: Equation Editor 3.0 and Microsoft Graph 97. A document created on this computer in Microsoft Word 7.0 contains Equation Editor 3.0 and Microsoft Graph 97 objects, even though these programs were installed by Word 97.
• Computer 2 has only Microsoft Word 7.0 installed. Therefore, it has Equation Editor 2.0 and Microsoft Graph 5.0 available. If you take the document created in Microsoft Word 7.0 on computer 1 and open it in Microsoft Word 7.0 on computer 2, you receive the error messages described in this article when you double-click an equation or graph object to edit it.
