Vision4D Network License setup

This article describes the activation and configuration process specifically for network licenses.


As described in this article on general software activation, arivis Vision4D is protected by a 3rd party license management software. This license management is based around the concept of keys that grant users access to the software and specific features thereof. The key or license can come in a 2x2 major distinctions.

First, licenses can be either

  • Soft licenses (SL) which use keys that are generated from, and attached to, a specific computer, or
  • Hard licenses (HL)  which have the keys embedded in a USB "Dongle" that can be manually moved from machine to machine as needed

And in either of those cases, the license can also be

  • Fixed, where the license is only available on the machine where it is located, or
  • Floating (network), where the license is attached to a specific computer but distributed out  to clients on the same network

Hard keys do not require activation as the license is already activated on the dongle when shipping, but soft licenses must be activated to lock the key to the user's computer. Network licenses need only be activated once on one computer that from then on serves as the license server. Floating licenses may require some additional configurations on both servers and clients to permit the distribution of the license.

Selecting a License server

The first and most important thing to note with network licenses is that the license must be based on a single computer.

That computer doesn't need to be a Server in the typical sense of the term, but it should definitely be a computer on the same network as the clients and it should preferably be a computer that can be left on so that clients are always able to access it. In that respect, putting the license server on a server computer is usually preferable.

The license server computer does not need to be able to run arivis Vision4D, it just needs to be able to run the license distribution tool. The License Server can be installed on either Windows or Linux machines.

Installing Floating Licenses on Windows Computers

On Windows computers, the License Tool can be installed as part of a Vision4D installation, or stand-alone using this link.

Once downloaded, the process is as follows:

  1. Install the License tool on the license server computer
  2. Open the License tool and activate the license if you are using a Soft key, or plug in your dongle in the computer

In most cases, this will be all that is required. The License server will start and any installation of arivis Vision4D on computers on the same network should be able to see the license when launching the application. However, in some cases, some additional network configuration may be required.

Installing Floating License on Linux Computers

On Linux computers, a generic Sentinel driver is available for several Linux distributions here, which should be all that's needed for Hard keys. To use a software license key (SL key) you can download the License Tool for Linux here.

Once downloaded, the process is similar to Windows computers, but activation will require a Windows computer, even if that computer will not be used as a server:

  1. Install the License tool on the server computer
  2. Plug in the dongle if you have one,  or follow the detailed instruction in this document to activate the license.

And again, in many cases that will be all that is required, but check the network configuration instructions below.

Network Configurations for Floating Licenses

The license server broadcasts available licenses on the network to which it is connected for clients to see when Vision4D is started. This broadcast is done through a specific network port, which must be open on both the server and clients. Please ensure that port 1947 is open for TCP/IP on any firewall on both the server and client computers. You can test that the port is open using a Ping command to that specific port. If the ping does not work, please contact your IT support team.

The clients must also be on the same network as the server machine. This means that, for users who wish to access the license while working remotely, a Virtual Private Network may need to be set up for the clients to appear to be on the same network.

Additional License Management Tools

The License Tool allows the user to do several things, like activating or transfering license, but some additional options are available to check the license status, monitor license usage, or limit who can access the license. In either Windows or Linux machines, these additional tools can be accessed by opening a web browser and entering this address:


Here, users can use the links on the left to check the status and validity of all licenses available on the current computer, check the access log to monitor usage, and use the Configuration tools to specifically instruct a machine to actively seek or block connections for specific IP addresses.


In most cases, network license configurations are relatively quick and easy, but if you have issues accessing the license, please check our troubleshooting article for more information or use the downloadable version of this article below which also contains more details.
