Understanding the HydroCAD User Count

What is the User Count?

When you run HydroCAD, it maintains a count of the number of people currently using the program. Each time you start the program, a message such as "User 1 of 2" appears in the upper portion of the screen. The first number (1) is your current user number, and the second number (2) is the number of licensed simultaneous users.

What happens when I reach the licensed user count?

If the maximum number of users has already been reached, you will not be allowed to enter the program   One person will have to exit from the program before you will be able to run HydroCAD. 

How is the user limit determined?

For HydroCAD 10.2 and later, we issue a single license code which is provisioned for the total number of users you have purchased.  If you purchase additional users, the user limit is automatically configured the next time you start HydroCAD, with no change to the license code.

For HydroCAD 10.1 and earlier, a separate serial number is issued for each user you purchase. A single-user license will have one serial number, which is entered in the Settings/Serial Number screen. If you purchase additional licenses, and elect to use license pooling, the additional serial numbers are added to the same screen.

How many users do I need?

You need to have enough licenses (users) to support the number of individual who will be using the software simultaneously. As a general guideline, this will be approximately one-half of the total number of people who will ever be using HydroCAD.  For example, is you have 5 engineers who need to use HydroCAD, dividing by 2 and rounding up, you would need 3 licenses to meet their needs.  If their usage is lighter than normal, you might only need 2 users.  If the usage is higher than normal, 4 licenses might be required.  You would need 5 licenses only if all 5 individuals will need to use HydroCAD at the same time.  See the table below for general recommendations.
