: It is officially supported on Windows 10 and Windows Server 2019 . While it can run on Windows 11 and Windows Server 2022, these are not yet officially supported. Alternative: Tekla Model Sharing

Trimble has shifted its focus to Tekla Model Sharing as the primary solution for collaborative work. The Multi-User Server remains a functional option for teams working in a single office location, but you must select Tekla Structures 2020 in the download portal to access the installer.

and can be used with models from previous Tekla Structures versions. Network Requirements : Uses TCP port by default (this must be opened in your firewall). IP Address : The server computer should have a fixed (static) IP address Performance

The remains a critical and reliable component for collaborative modeling within a local network. While newer cloud-based solutions exist, this version's unique cross-compatibility makes it the go-to download for teams of all sizes, regardless of whether they are using Tekla Structures 2020 or the latest 2026 version.

It functions as a Windows service, which means it starts automatically when the server computer is turned on and runs in the background without requiring a user to log in. This invisible yet critical component performs several essential tasks:

If you tell me which you're using (e.g., 17.0, 18.0, 19.0), I can confirm which Multi-User Server version is actually required and the safest way to get it.

Even with a successful , you may encounter issues. Here are the top three:

According to Tekla’s official documentation, , which is the version compatible with Tekla Structures 2020, will also work seamlessly with newer Tekla Structures versions (including up to 2026) as well as older ones. The reason you don't see a newer "Multi-User Server" listed as a download for each new Tekla version is that the underlying functionality of the server has not seen drastic changes, making 2.5.0 the universal and stable choice.

: Run the installer with administrator rights. The default location is C:\Program Files (x86)\Tekla Structures Multi-user Server .

The is a crucial utility for structural engineering teams who need to collaborate on the same 3D building information modeling (BIM) projects simultaneously. While newer cloud-based collaboration tools exist, many localized engineering setups, corporate intranets, and legacy workflows rely heavily on a dedicated local multi-user server to maintain high-speed modeling environments without relying on external internet bandwidth.

Before you install the Multi-User Server 2.5.0 on your server machine, keep these best practices in mind:

Once installed, the server needs to be configured to allow inbound connections from Tekla Structures client workstations.

Save the model folder to a shared network drive accessible by all team members (read/write permissions required).

No. The Multi-User Server is free software. However, each client machine connecting to it must have a valid Tekla Structures license or subscription.

To install Tekla Structures Multi-User Server 2.5.0, follow these steps:

The installer configures the Multi-User Server to run as a Windows service. This means the service is always available and is automatically started whenever the server computer is started. There is no need to log in or manually start the server each time.
