# Equation Editor: WinWord 1.x Equation Does Not Appear

**ID: Q78749**

The information in this article applies to:

- Microsoft Equation Editor version 1.0

## SUMMARY

You can convert equations originally created in Microsoft Word for
Windows version 1.0, 1.1, or 1.1a to Word for Windows version 2.0;
however, the Equation Editor may not start up when you double-click
the equation.

## MORE INFORMATION

If you embed an equation in a Word for Windows version 2.0 document,
double-clicking the equation should open the Equation Editor. This
does not always occur if the equation was converted as part of a Word
for Windows 1.x file.

Sometimes after you double-click the equation, the Equation Editor
opens with a blank window, indicating that no equation exists in that
particular location.If this problem occurs, the equation is also
deleted from the text of the document. To correct this problem, use
the following steps:

1. Exit the Equation Editor, and close the file without saving

```
changes.
```

2. Open the file. From the View menu, choose Field Codes (unless
```
Field Codes are already turned on).
```

3. Position the insertion point immediately after the existing field
```
code for the equation and retype the equation. Be sure to use CTRL+F9
to insert the special field code braces.
```

After you retype the equation field, the Equation Editor should work
correctly.

## MORE INFORMATION

Microsoft is researching this problem and will post new information
here as it becomes available.
