Frequently Asked Questions
The Subscription license has a significant lower up-front cost with a low annual fee to keep the software active. It automatically renews each year until you cancel. You’ll get automatic software updates and free technical support. You will always have the latest version.
The Perpetual license is a one-time cost and you will own the software forever as it never expires and includes automatic software updates. Adding the optional Annual Maintenance at check-out provides you with technical support, just like the Subscription license. The Annual Maintenance is a single flat fee of $99 per year, until cancelled.
Both licenses are on-premise installations. The software installs and runs on your computer, not on the Internet. Your data files will always remain intact, on-premise, on your computers, even if your Subscription expires.
So which is right for you?
That’s entirely up to you. Some buyers prefer to blend the subscription cost into their annual operating budget. Others prefer to pay it up front. The break-even point is about three years.
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 includes a built-in floating (network) license server that 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.
This is easily accomplished right in your software and comes standard with Subscription and Perpetual licenses.
