OFFXP: "MT Extra Font Is Not Available" Error Message When You Insert or Activate Equation Editor Object

When you insert or activate a Microsoft Equation Editor object in your document, you receive the following error message:

You may receive this error message if you set the Equation Editor feature in the Microsoft Office XP: Selecting Features dialog box to Run all from Network or Run from Network.

If you set either the Microsoft Office or the Office Tools feature to Run all from Network, the Equation Editor feature will be set to Run from Network.

If you receive this error message, click OK. Equation Editor will work as expected.

You only receive this error message once during each session of the Office program that you are using. If you quit, restart the Office program, and then insert or activate an Equation Editor object, you receive the error message again.

To prevent the error message from appearing, follow these steps:

1. Quit all Windows programs.
2. Click Start, point to Settings, and then click Control Panel.
3. Double-click Add/Remove Programs.
4. Double-click the Office XP entry in the list of installed programs.
5. Click Add or Remove Features in the Microsoft Office XP: Maintenance Mode dialog box.
6. Click the plus (+) sign next to the Office Tools feature.
7. Change the installation state of the Equation Editor feature to Run from My Computer.
8. Click Update Now.
9. Click OK to the message that advises you that Setup has completed successfully.

You now can insert or activate an Equation Editor object without receiving the error message in the "Symptoms" section of this article.
