Tekla License Server 2022 hardware recommendations

If you have legacy on-premises licenses, you must install a license server on your own hardware to use them.

The information on this page is not valid for Tekla subscriptions.

We recommend that you always upgrade your on-premises license server to the newest available version. Each license server version is compatible with several versions of Tekla Structures. For installation instructions, see Installing Tekla on-premises license server.

Operating system

The FlexNet licensing system for Tekla Structures runs on these operating systems.

  • Microsoft Windows 11
  • Microsoft Windows 10
  • Microsoft Windows Server 2022
  • Microsoft Windows Server 2019

Both 32-bit and 64-bit operating systems are supported.

It is a best practice to install Tekla License Server on a server-based OS. If there is no local area network in your company, you can install the license server on each computer that Tekla Structures is running on, and activate one license on each computer.

License server hardware

The server that is used as Tekla License Server does not have to be very efficient or have maximum performance. The reliability of the server and the network connection are more important than performance.

Users cannot run Tekla Structures without access to a subscription or license. to minimize the risk of disrupting the work of your users, we recommend running any license server that is used by multiple users on hardware and an operating system intended for servers. Servers are designed to operate properly continuously without rebooting, unlike workstations.

Virtualization platforms

These virtual machine platforms are supported for Tekla License Server.

  • Citrix XenServer 8.0
  • everRun 7.8
  • Microsoft Windows 10 Hyper-V
  • Microsoft Windows Server 2019 Hyper-V
  • Oracle Virtual Box 6.1
  • Parallels Desktop 15.1.2 for macOS 10.15.4
  • QEMU-KVM (Host OS: CentOS 8)
    • Hypervisor: qemu-kvm-ev-4.2.0
    • Hypervisor Services: libvirt-daemon-kvm-6.0.0
    • Virtual Machine Manager: vmm v2.2.1
  • VMware ESXi 6.5 and 6.7
  • VMware Workstation 16.1.0

Linux or Unix based servers are not supported. Directly deploying the Tekla License Server in cloud environments is not supported.

Backups

If the activated licenses are deleted or if the license server computer suffers a hardware failure, you need backups to recover your licenses.

Keep your on-premises licenses safe. Keep a copy of the license entitlement files that are sent to you by email. Back up your activated licenses to a separate backup location.

If activated licenses are lost and no backups are available, replacement licenses can be ordered according to the terms of the end-user license agreement.

Internet connection

Your license server contacts Trimble’s activation server when you activate deactivate, or repair licenses. Users who work outside of the office might also need to connect to the license server.

Direct communication from the license server computer to the internet must be allowed while your license server contacts Trimble’s activation server. The activation communication is done using simple object access protocol (SOAP) over HTTPS on TCP port 443. Your firewall should not block any incoming or outgoing information during the activation. To allow the activation communication, use the activation server address in your firewall settings: https://activate.tekla.com:443/flexnet/services/ActivationService?wsdl

The computers where users use Tekla Structures connect directly to the license server for on-premises licenses. If users work outside the office, they must be able to connect to the license server remotely, such as through a VPN, or borrow a license while they are connected to the license server in the office network. If you also have Tekla Structures subscriptions, users outside your office network can use the subscriptions without additional setup. Tekla Structures subscriptions are provisioned to the users directly from Trimble's cloud service.

The license server can be used in networks that use IPv4, IPv6, or both the IPv4 and IPv6 protocols.

Other infrastructure

Tekla Structures must be able to contact the license server to reserve a license when it starts up. Your firewall must allow the communication between the server computer and the computers where users use Tekla Structures.

You must allow the applications tekla.exe and lmgrd.exe to operate through the firewall. The applications are located in the ..\Tekla\License\Server folder.

Do not change the MAC address of the network adapter on the computer that is running the license server. If you are using a virtual environment, ensure that you are using static MAC addressing instead of dynamic MAC addressing.

The computer running the license server must have a static IP address.
