When you install MathType you can either install it unlocked or in a 30-day evaluation mode. You must have a valid registration number to unlock MathType. If you purchased MathType this number is on the registration card inside the MathType box. If you bought MathType online and downloaded it, the registration number is on the payment confirmation Web page and also in the order confirmation e-mail you received. Enter your personal information and the registration number, and then click OK to continue.

If you don抰 have a registration number you can evaluate MathType by choosing the Evaluate MathType for 30 days option. The full version of MathType will be installed, and you will enjoy the same functionality as the unlocked version. Towards the end of the evaluation period you抣l start receiving messages when you start MathType informing you how much of the evaluation period remains. You can unlock MathType at any time with a valid registration number (you don抰 need to re-install). Choose the Register MathType?command on MathType抯 Help menu and enter the registration number into the dialog that opens.

Once the evaluation period has expired MathType starts running in MathType Lite mode. This provides a level of functionality similar to our Equation Editor product. An added bonus is that MathType Lite is better for collaboration
with MathType 5 users than Equation Editor.
