An evaluation installation is limited to 30 days. Up to five users can thus use SwyxWare at the same time. After purchasing SwyxWare you can enter a valid license key within this 30 day period using SwyxWare Administration and after that request a permanent license key via SwyxWare Administration. You will find information on how to receive such a key in the SwyxWare documentation for administrators, chapter “SwyxWare Installation“, section “Configuring SwyxWare“.
