How To Insert Equation When Equation Editor Greyed Out [Solved]

If you open up certain types of Microsoft Word documents you will find you’re unable to insert an equation as the icon used to insert equations into your document cannot be clicked and looks greyed out.

Something that looks a little like this:

Equation Editor icon in Microsoft Word 2011 for Mac greyed out
Install and setup Salesforce Code B...
Install and setup Salesforce Code Builder

Thankfully the solution is quite simple.

To get around this problem simply save the Word document as a .docx file as the current working document will have [Compatibility Mode] enabled (as seen in the screenshot above).

Once you’ve saved the document into a compatible file you’ll have no problems clicking on the Equation Editor icon and embedding your juicy equations in.
