If there's no License Key File, the installation wizard will generate 30-days trial key. Please keep it in mind, when you re-install eWall at new location: it will generate the trial License Key File that you will need to replace with your personal License Key File, available in Customer area.
After installation please visit the Getting started section of online manual, that will pass you through the setup process.
Download the new version and install over the existing. Follow the installation wizard instructions.
