TESSY is available with a node-locked license, or with a floating license, or with a CI license.
The node-locked license restricts the use of TESSY to the PC the license is issued for. It is not a dongle license.
One or more floating licenses are administrated by a Floating License Server (FLS). At the same time, you may use TESSY as many times as the amount of licenses the FLS disposes over.
The Continuous Integration (CI) floating license is intended for TESSY in CI/CD pipelines. It allows TESSY only to run in headless mode, i.e. without using the graphical user interface. Only for Floating License Servers (FLS) on Windows. TESSY on Linux can use CI licenses of a FLS under Windows. At least one TESSY floating license of the same version must be present on the FLS.
