This report outlines the acquisition and installation process for the Siemens PLM License Server (often referred to as Siemens License Server or SLS) on Windows 64-bit operating systems.
Crucial Note: Siemens Industry Software does not provide the license server software as a public download. It is restricted software available only to active customers with a valid support contract.
Compatibility between the License Server version and the Software version is critical.
Unlike stand-alone licenses (locked to one machine), network floating licenses require a centralized server. The Siemens PLM License Server (based on FlexNet Publisher from Flexera) performs three critical jobs:
The Win64 version runs on Windows Server 2016/2019/2022 (and some Windows 10/11 Enterprise builds for test environments).
Before searching for the download, it is crucial to understand what this software does. The license server (often referred to as "Siemens PLM License Server" or "UGS License Server" based on older naming) is a background service that manages floating network licenses.
The Siemens PLM License Server (typically based on the Siemens Digital Industries Software Licensing Tool or legacy FlexNet Publisher technology) is a critical backend service that manages and distributes software licenses for Siemens’ portfolio of Product Lifecycle Management (PLM) applications. These applications include NX, Teamcenter, Solid Edge, Tecnomatix, and Simcenter.
For Windows 64-bit (Win64) environments, this server software allows organizations to host licenses on a dedicated machine, enabling multiple client workstations to check out and return floating licenses over a network.
