How do you disable MathType in Microsoft Word?
It's not real clear exactly what it is you want to do. MathType
is a separate program from Word, so if you don't want to use it,
simply stop using it. If you no longer want the MathType
toolbar/menu (or Ribbon tab in Word 2007), you can either uninstall
MathType or remove the Word add-in from Word's Startup folder.
If you didn't really mean the full MathType product, but rather
meant Equation Editor (a subset of MathType, included with
Microsoft Office as "Microsoft Equation 3.0"), you can do that by
running the Office installation program and de-selecting Equation
Editor.
