Yes. The Single-Seat License allows you to install and use your software on up to two of your devices. For example, you can use it on your work computer and on your personal computer at home or a laptop.

The Five-Seat Bundle provides you with five (5) individual seats that can be installed and activated simultaneously. They can be used on multiple computers, anytime, anywhere.
The Five-Seat Bundle offers a tremendous cost savings and is an excellent choice for firms with multiple offices and/or work-at-home employees who need unrestricted access to the software. See, “Flexible Licensing” below for additional cost-saving benefits.
All Hydrology Studio software allows you to move licenses from one computer to another with just three mouse clicks. Your software can be installed on as many devices as you want, but you can only use it simultaneously up to the number of seats purchased. (Two for the Single-Seat or up to five with the 5-Seat Bundle).
For example, if you purchased a Single Seat License but have 4 users, all users have access, but only 2 can use the software simultaneously. At any time, you can simply log-out from any one of the installs and log-in on another computer; in a branch office, at home, a laptop, or on a new computer for example.
The Trial versions have some minor functional limitations. For example, you will not be able to save any of your project files. All printed reports will be watermarked. There may also be limits on inputs. However, you will certainly be able to give them a good test run.
