Tekla Structures Multiuser Server 2.5.0 is the latest recommended version for all Tekla Structures users, functioning as a background service that allows multiple collaborators to work on the same model simultaneously. Key Features & Compatibility
The 2.5.0 version is both backward and forward compatible, meaning it works with older versions of Tekla Structures (such as 2017 or earlier) and remains functional for newer releases up to the current date.
Universal Use: Trimble recommends using the latest 2.5.0 server version regardless of which Tekla Structures version your team is currently using.
Fixes: This specific version includes a critical drawing lock fix and introduces IPv6 support (effective for Tekla Structures 2017 and later).
Hardware Requirements: The server does not require high-performance hardware and can even run on the same machine as the Tekla License Server, provided they use different TCP ports. Download and Setup To obtain the installer, follow these steps:
Locate the File: Log in to the Trimble Downloads portal using your Trimble Identity. Select the 2020 version of Tekla Structures; the Multiuser Server 2.5.0 installer is typically listed under the All Downloads section for that year.
Installation: Run the installer on a central machine (preferably a company server) that remains powered on at all times.
Service Configuration: Once installed, ensure the Tekla Structures Multiuser Server service is marked as "Running" in the Windows Services panel (Control Panel > Administrative Tools > Services).
Network Setup: Ensure TCP port 1238 (default) or your custom port is not blocked by your firewall. Transition to Tekla Model Sharing
While the multiuser server 2.5.0 remains supported for local network collaboration, Trimble has transitioned its primary development focus to Tekla Model Sharing. Model Sharing is a cloud-based solution that is generally more robust for teams in different physical locations and reduces the risk of data corruption compared to the traditional local server setup.

Guide to Tekla Structures Multiuser Server 2.5.0 Tekla Structures Multiuser Server 2.5.0 is a companion service that allows multiple users to work on the same Building Information Model (BIM) simultaneously over a local area network (LAN). This version is designed to be backward and forward compatible, meaning it works with older and newer versions of Tekla Structures, including version 2020 and beyond. Download and Installation
To set up or update to the 2.5.0 version, follow these steps:
Access Official Downloads: Visit Trimble Downloads and sign in with your Trimble Identity.
Locate the Package: Search for "Tekla Structures Multiuser Server" under the All Downloads section of your specific version (e.g., Tekla Structures 2020). Run the Installer:
Install it on a computer that will act as the server (this machine must remain on at all times).
The default installation path is typically C:\Program Files (x86)\Tekla Structures Multi-user Server. Verify Service Status:
Open Windows Services (Control Panel > Administrative Tools > Services).
Ensure the Tekla Structures Multiuser Server service is listed and its status is "Running". Key Features of Version 2.5.0
Broad Compatibility: Compatible with Tekla Structures 17.0 up to current versions.
Infrastructure Support: Now supports IPv6 protocols in addition to IPv4. Tekla Structures Multiuser Server 2
Drawing Stability: Includes specific fixes for drawing locks, particularly effective for versions from 2017 onwards.
Lightweight: Does not require high-performance hardware and can run alongside the Tekla License Server as long as separate TCP ports are used. Configuration Tips
Tekla Structures Multi-user Server 2.5.0 is a critical utility that allows multiple users on the same Local Area Network (LAN) to work simultaneously on different parts of a shared model. While newer versions of Tekla Structures are frequently released, version 2.5.0 remains the standard compatible server for version 2020 and later. Tekla User Assistance Download & Update Information
The multi-user server is not typically a standalone update but a specific software package found in the Trimble Downloads Tekla User Assistance : Log in with your Trimble Identity to access the Trimble Downloads Version Selection : To find the 2.5.0 installer, select as the Tekla Structures version on the download card. Compatibility
: This version is backwards and forwards compatible, meaning it works with older versions and the newest Tekla Structures versions. Tekla User Assistance Key Features
The multi-user server functions as a lightweight service (running as xs_server.exe ) that coordinates changes across the team. Tekla User Assistance Real-time Collaboration
: Enables simultaneous editing of different model parts over a LAN. Conflict Prevention
: Uses central coordination of "write locks" to ensure users do not overwrite each other's data. Session Management
: Efficiently handles users joining, leaving, or synchronizing with the central model. IPv6 Support : Effective for Tekla Structures 2017 and newer. Drawing Lock Fixes
: Includes critical fixes for drawing locks when multiple users are active. System Requirements & Infrastructure TCP 2700 – Main MU Server port TCP
The server does not require high-performance hardware and can often run on the same machine as the Tekla License Server if different TCP ports are assigned. Tekla User Assistance Operating Systems : Officially supported on Windows 10 Windows Server 2019
. While it can run on Windows 11 and Windows Server 2022, they were not yet officially supported as of recent technical documentation.
: Requires a fixed IP address for the server computer. All client computers must be on the same network with unique IP addresses and identical subnet masks. : The service uses TCP port 1238
by default; this must be opened in the firewall for incoming communications. Tekla User Assistance Implementation Advice Multi-user vs. Model Sharing
: If your team is in different physical locations (not on the same LAN), Trimble recommends using the cloud-based Tekla Model Sharing instead of the multi-user server.
: Regularly schedule backups of the model data to a separate physical machine, as the server itself only manages the session, not the physical file redundancy. Tekla User Assistance setting up a second instance

If you install the full Tekla Structures suite via the "Setup" executable, look for the "Network Tools" checkbox. The Multiuser Server 250 is typically included in the \Tools\Multiuser subfolder of the installation media.
Open these in Windows Firewall (inbound/outbound).
C:\TeklaStructures\MultiUserServer\250\The Multiuser Server is a lightweight, dedicated server application that facilitates real-time collaboration. The "250" designation refers to the concurrent user connection limit. Unlike the standard server versions limited to 20 or 100 users, the Multiuser Server 250 is designed for enterprise-level teams and mega-projects involving up to 250 simultaneous connections.
