## MathTime Professional 2 Fonts Updates

It has been nearly three years since MTPro2 was first released. During that time a few small bugs have been discovered and fixed, and a few symbols and characters have been reworked.

Below are two update file sets, one for MTPro2 Complete and the other for MTPro2 Lite. These are supplements to the original release of MTPro2 and are not complete installation images. In other words, if you do not have a copy of MTPro2 installed already, do not use these update sets.

If you are using PCTeX, download the appropriate file and open it in PCTeX. This will install the update automatically.

If you are not using PCTeX, download the appropriate file and then follow the instructions found at font installation.
