TracePro, RayViz, and OSLO: License Options

When purchasing TracePro®, RayViz™, or OSLO®, you choose from four license types: single-user USB, single-user soft, network USB, and network soft. The right choice comes down to two decisions: where the license lives (one machine or a shared server) and how it's stored (a portable USB dongle or a machine-locked soft license). This page walks through both decisions and the practical considerations that usually settle them.

Single-user vs. Network

Single-user
  • The license is stored on a PC or in a dongle plugged into a local PC. The software runs on the same computer/machine. 
Network
  • The license is stored on a central server in the network. It is used by PCs as a floating license. 
  • Network License Server - Operating System Options

USB license vs. Soft license

USB License
  • License is stored on a physical USB dongle. 
  • Portable - can move to another computer. 
Soft license
  • Linked to the computer’s hardware/software. 
  • Not portable - only works on the system for which it was created. 
  • Deactivates if moved to a different computer or if key system identifiers change. 

Which combination fits your team?

A single engineer, one workstation: a single-user soft license is the simplest: no dongle to manage, activated directly on the machine. Choose single-user USB instead if you expect to move between machines (office workstation and lab PC, for example).

A team sharing seats: network licenses float: any PC on the network can check out a seat from the license server, up to your seat count. This maximizes utilization when more engineers than concurrent users need access. See Network License Server – Operating System Options for supported server environments.

Secure or air-gapped environments: all license types work without internet access; license updates can be transferred by file. Defense and aerospace customers routinely run TracePro and OSLO on isolated networks.


Special considerations for all licenses

  • License Replacement: Lost or damaged USB dongles and deactivated Soft licenses can be replaced. 
  • Virtual Machines: Licenses are supported. 
  • Remote Access: Works with Windows Remote Desktop (other remote tools should be tested). 
  • No Internet Access: Licenses work offline, though some update tasks may require alternative methods. 
  • Multiple Instances: You can run multiple instances of the software on one computer, counting as one license. 
  • Multiple Products 
    • With a combined license, one license covers all products. 
    • Single-product licenses can be used on separate computers. 
  • Maintenance and support: every license includes a maintenance and support subscription period. An active subscription covers updates to the latest release, license replacement, and engineering support; see the Support Policy for what's included as subscriptions expire.
