Get a License

VIESUS on-premise is commercially licensed. This page explains what to obtain from Viesus AG before installing.

VIESUS on-premise products are commercially licensed. Contact [e-mail] to purchase or request a trial — Viesus AG will send you the software package along with your license details.

A GUID license runs VIESUS across multiple machines, containers, or VMs — a unique GUID is delivered with your software package and passed at runtime. Request it when arranging your license.

An Activation Key binds the license to a specific machine: you install the software, generate a request file from the target machine, and exchange it with Viesus AG for an activation file that unlocks the library on that machine.

See Licensing for how each model works, full activation steps, and renewal.

Using VIESUS Cloud? No license or installation is required. See Quickstart: Cloud to get started.
