The Tekla Structures Multiuser Server 2.5.0 remains a critical component for teams collaborating on the same building information model (BIM) within a local network. While Trimble now emphasizes Tekla Model Sharing as its primary cloud-based collaboration tool, version 2.5.0 continues to be the recommended server software for on-premises multi-user workflows. Download and Compatibility

Despite being several years old, the 2.5.0 version is both backward and forward compatible.

Updating from an older MU Server (e.g., 240 → 250)

1. Stop the existing MU Server service

   • Open Services (services.msc) → Find Tekla Structures Multi-User Server → Stop.

2. Back up old server folder (optional)

   • Copy C:\TeklaStructures\MultiUserServer\240\ to a backup location.

3. Install Tekla Structures 2024 (or extract MU Server 250 as shown above). The Tekla Structures Multiuser Server 2

4. Update the service (if needed)

   • After installation, the service Tekla Structures Multi-User Server will point to the new version automatically.
   • If not, run manually:

     sc config "Tekla Structures Multi-User Server" binPath= "C:\TeklaStructures\MultiUserServer\250\TeklaStructuresServer.exe"
     

5. Start the service again.

8. Important Warnings

• Never mix versions – All users and the server must be on Tekla Structures 2024 + MU Server 250.
• No backward compatibility – Models saved with version 250 cannot be opened with older MU servers.
• No standalone download – Always get MU Server from the official Tekla 2024 installer.
• License required – The MU Server itself is free with a valid Tekla Structures license, but each client needs a license.

Lock server port (default 2701)

LOCK_PORT=2701

Hardware & network recommendations

• Server should have a fixed IP address and be on a reliable LAN with low latency.
• Ensure unique IPs and identical subnet masks for client computers.
• Use scheduled backups for model data and store backups on a separate machine.
• The server does not need extreme CPU/GPU power—network reliability and disk I/O for the file server hosting the master model are more important.

Installation (typical steps)

1. Sign in to Trimble Downloads and download the Multi-user Server installation file.
2. Run the installer (by default installs to C:\Program Files (x86)\Tekla Structures Multiuser Server).
3. The installer configures the server as a Windows service (Tekla Structures Multiuser Server) that starts automatically.
4. Installation logs are written to C:\ProgramData\TeklaStructuresServer\xs_server.log.

Supported OS and compatibility

• Officially supported: Windows 10 and Windows Server 2019.
• Possible (not officially supported): Windows 11 and Windows Server 2022.
• The same Multi-user Server 2.5.0 installer is compatible across multiple Tekla Structures versions; Tekla recommends using the latest multi-user server regardless of client Tekla version.

Ports (default – do not change unless necessary)

• TCP 2700 – Main MU Server port
• TCP 2701 – Lock server port

Open these in Windows Firewall (inbound/outbound). Stop the existing MU Server service
