FAQ

What are the differences between the Subscription and Perpetual licenses?

The Subscription license has a lower up-front cost with a low annual fee to keep the software active. They automatically include software updates and technical support. You will always have the latest version. If your subscription expires, the license will be revert to the Trial Version with limited capabilities. To continue using your software, you will need to place an order for a new subscription and reactivate your installed software.

The Perpetual license is a one-time cost and you will own the software forever as it never expires. You may optionally add Annual Maintenance at check-out which provides you with automatic program updates and technical support, just like the Subscription model. The Annual Maintenance fee is about 20 percent of the purchase price.

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.

Can I use the software on my home computer?

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.

What's included with the Five-Seat Bundle?

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 employees who need unrestricted access to the software. See, “Flexible Licensing” below for additional cost-saving benefits.

Please explain “Flexible Licensing”

Hydrology Studio uses a simplified floating license server that allows you to move licenses from one computer to another with just a few 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.

For example, if you purchased 5 seats and have 8 users, all users have access, but only 5 can use the software simultaneously. At any time, you can deactivate one (or any) of the installs and reactivate it 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 with an easy-to-use license management console, available for both Subscription and Perpetual licenses; Single-Seat and Five-Seat Bundle.

What are the limitations of the Trial Versions?

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. There is no time limit.

How long before I receive my License Key(s)?

Our online store is fully automated, so you will receive your activation codes instantly via email after you place an order. Your order confirmation will also include direct links to install your software.

How do I get the updates?

For Subscription licenses, they are automatic. There’s nothing you need to do.

For Perpetual licenses, if you add the annual maintenance to your order it’s also automatic, just like the Subscription licenses.

Your software checks for new updates each time it’s launched. If one is available, you will be prompted to update. Just click [Ok] and seconds later your software will start as usual, but will be the latest version.

How do I install the software?

Installation is a piece of cake. Just click on any of the “Download/Install Free Trial” links throughout this website. You’ll be asked to first setup your account with a username, password, etc. After that, just click the [Install] button. Your purchase receipt will also contain buttons to directly install the software. No need to log in.
