Program needs Java 1.8 or later.
Windows/Linux: If you do not have Java, you can download Java Runtime Environment installer for free at

  • Mac OS X - ensure you have Oracle JDK8 installed. Download zipped Mac OS X application. In Finder, right click downloaded file and select "Open". Message that FFDec comes from unidentified developer will appear. Click "Open" button in that dialog. (Look here for details)
