IMPORTANT: This article contains information about editing the Registry. Before you edit the Registry, you should first make a backup copy of the Registry files (System.dat and User.dat). Both are hidden files in the Windows folder.
When you double-click the MathType icon or MathType object in a Word document, Equation Editor runs instead of MathType.
MathType 3.0 Equation is not available to select from the Object dialog box (Insert menu) in Word.
Math Type version 3.0 is a third-party application, by Design Science, Inc., that you can purchase separately for use with Word.
If you select MathType 3.0 Equation in the Insert Object dialog box, Microsoft Equation Editor version 2.0 may run instead of MathType version 3.0.
When you open a document that contains MathType objects, the objects are automatically converted to Equation Editor objects.
You are using MathType (version 3.0 through 3.0e) which may not be registered as the default equation editor in the Registry (Windows 95) or the Reg.dat (Windows 3.x) file. This problem typically occurs when you install Equation Editor during a complete/custom installation of Word.
Design Science has confirmed this to be a problem with MathType 3.0. This problem has been corrected in MathType, version 3.1.
Upgrade to MathType version 3.1. For more information, contact MathType technical support by using one of the following methods:
