Microsoft equation 3.0 has suddenly disappeared from my object list in Word. Any help would be appreciated. This thread is locked. You can follow the question or vote. Microsoft suggested affected users can 'edit Equation Editor 3.0 equations without security issues' with Wiris Suite's MathType, a commercial application that costs $97 ($57 academic). They did not specify the basis upon which the phrase 'without security issues' was provided, but MathType seems to have a clean public security record so far. Microsoft recommends turning off Auto-recovery in Word. Note, however, this is a prevention step and will not repair equations that have already become non-editable pictures. Math equations that are created by Microsoft Equation Editor 3.0 are no longer supported on Microsoft Office 2010 SP2 Onward since January 2018 due to security issue. Such equations will not be displayed when the 'MT Extra' font is missing from the local system.

Issue
Many users become concerned when their equations are replaced with empty boxes or appear in gray-shaded boxes. Double-clicking these boxes will launch MathType and display the equation, and the equations will print correctly, but the equations are not displayed properly in Microsoft Word.
Reason
The 'empty boxes' behavior is a feature in Microsoft Word called 'Picture (or Image) Placeholders' designed to conserve RAM. The Picture Placeholders option helps minimize the amount of computer resources required to display a page and helps Word scroll multiple pages faster on-screen. So long as your computer does not have insufficient RAM, you can toggle this setting so the equations in your document display on-screen.
The 'gray-shading' behavior is a setting called 'Field Shading' designed to make finding equations and other OLE objects easier when they can be difficult to see among surrounding content.
Solution
As these are features of Word, it is advisable to refer to Word's Help files to learn more about them and how they are activated.
If none of the equations or other graphics in your document display (Windows only)
If you find that all of the graphics in your document are not being displayed, Picture (or Image) Placeholders is probably enabled. To turn this option off, do the following:
- Select
- Office button | Word Options | Advanced |Show document content (Word 2007)
- File tab | Options | Advanced | Show document content (Word 2010 and later)
- Uncheck the box for Image Placeholders or Picture Placeholders.
If this was the cause, unchecking this option will cause all the objects in the document to be displayed again.
If some or all of the equations or other graphics in your document display in a gray-shaded box
If you find that some or all of the graphics in your document display in gray (or striped) boxes, Field Shading is probably enabled. To turn this option off, do the following:
- Select
- File tab | Options | Advanced | Show document content (Word 2010 and later)
- Under Field Shading, select Never from the pull-down menu.
If this was the cause, setting this option to Never will cause all the objects in the document to be displayed properly again.
