How to Fix the MathType MT Extra(True type) Font Issue
If you use MathType, a powerful equation editor for Windows and Mac, you may encounter a warning message that says \"MathType requires a newer version of MT Extra\" when you launch the program. This message indicates that your system does not have the correct version of MT Extra, a font that contains many symbols used by MathType. In this article, we will explain why this problem occurs and how to solve it easily.
What is MT Extra(True type)?
MT Extra(True type) is a font that contains 145 characters, mostly mathematical symbols and Greek letters, that are used by MathType and other equation editors. The original version of MT Extra, which was distributed with many word processing, publishing, and test generation programs, contained only 43 characters. The enhanced version of MT Extra was included with MathType to provide more symbols and better compatibility with other applications.
Why does MathType need a newer version of MT Extra?
When MathType is launched, it checks the version of the installed copy of MT Extra. If an older version is installed, some of the expected characters will be replaced by empty boxes in equations. This can affect the appearance and functionality of your equations. To avoid this problem, MathType needs a newer version of MT Extra that matches its requirements.
How can I fix the MathType MT Extra(True type) font issue?
The simplest way to fix this issue is to reinstall MathType. This will ensure that the correct version of MT Extra is installed in your system. If you downloaded MathType and no longer have the installer, you can download another copy from the official website[^1^], but please make sure to download the version you are licensed for.
If you are familiar with the Fonts Control Panel and the use of File Explorer in Windows, or the various font locations in macOS, you could also manually install the MathType version of MT Extra after removing extra copies of MT Extra from your system. To do this, follow these steps:
Close all applications that use fonts, such as word processors or browsers.

Navigate to the folder where MathType is installed (usually C:\\Program Files\\MathType\\Fonts\\TrueType in Windows or /Applications/MathType/Fonts/TrueType in macOS) and double-click mtextra.ttf.
In the font preview window, click Install (in Windows) or Install Font (in macOS).
Restart your computer and launch MathType again.
