Single User License
When you buy a copy of Traverse PC, you are purchasing a single user license which allows one person at a time to use that license. If two or more people need to run Traverse PC at the same time, you need to purchase an additional license for each person or switch to a network license. See License Agreement.
You can request a courtesy license so that you can install Traverse PC on a second computer (home computer, laptop you take into the field, etc.). You can then run Traverse PC on either computer as needed. But remember, this is a single user license. Allowing two people to run a single user license of Traverse PC on two computers at the same time is a violation of the license agreement.
