To use any callas product on a computer, you will need to activate it first. This is true if you have bought a license key but also if you want to test the software through a trial. This article explains how the normal activation procedure for pdfToolbox SDK works and which steps you have to go through.


After filling in the form for the trial you will receive an email containing a download link for the SDK package, your trial license, and these activation instructions.
NOTE: The package is actually named pdfEngine


  1. Included in the library folder is a command line activation tool.

    Use the following command: ./activation_sdk --keycode <Name> <Company> <License key OR path to license file>
