To use Evince, you need a proper license key. You can obtain a free trial license key when you register as a member at www.prediktera.se and request a license through the login pages. If you have any queries about licenses, contact Prediktera at license@prediktera.se.

After installing Evince and running the program for the first time, a license wizard will appear where you can choose how to activate you license. If you have registered as a member at www.prediktera.se and have internet access at the time of installation, you may choose to activate your license simply by entering your login name and password. You may also choose to activate your license from text, by manually pasting the license key code which was sent to you by email upon purchasing a license or browsing for the license file on your computer.
