SYMPTOMS

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.


CAUSE

You are using MathType (version 3.0 through 3.0e), which may not be registered as the default equation editor in the Registry file. This problem typically occurs when you install Equation Editor during a complete/custom installation of Word.

To convert equations from Equation Editor objects into MathType equations, follow these steps:

  1. Start MathType and Word.


  2. In Word, open the document that contains your equations.


  3. Select an equation, and then click Cut on the Edit menu.


  4. Switch to the MathType window, and then click Paste on the Edit menu.


  5. Select the equation, and then click Copy on the Edit menu.


  6. Switch to Word and then click Paste on the Edit menu.


  7. Repeat steps 3 through 6 for each equation in the document.


Method 2

Update the registry by rerunning the MathType Setup program, and then follow these steps:

  1. Click Custom Installation.


  2. Select the MathType's OLE Registration option, and then click OK.


NOTE: Do not install the WordBasic Macros included with MathType. They were designed for use with Word for Windows 2.0 and do not work correctly in Word 97 for Windows.

Method 3

If you tried methods 1 and 2 and Equation Editor still runs instead of MathType, make the following modifications manually:

  1. Follow these steps to modify the Win.ini file:


    1. Click the Start button and click Run. Type "Sysedit" (without the quotation marks) in the Open box, and then click OK.


    2. In the Win.ini file, locate the [Embedding] section.


    3. Comment all lines in this section that begin with Equation. To do this, type a semicolon before each line that begins with the word, "Equation."


    4. Save and exit System Configuration Editor.


  2. Modify the Registry.
