HydroCAD® Stormwater Modeling - Since 1986
Note that all network and license management capabilities are included in the standard installation program. No separate software is required for these applications.
HydroCAD should not be run in Windows "Compatibility mode". HydroCAD is designed to run as a native application on all supported Windows platforms. Using "Compatibility mode" can cause hard-to-diagnose problems and should never be used! To verify your settings, right-click the HydroCAD icon and check the Compatibility tab.
Administrators' tip: If you are preparing a script for automatic installation on multiple computers, you may use "setup /silent" to perform a silent installation on each PC. If AutoCAD is present, the /silent option will automatically select the most recent version of AutoCAD for watershed import.
Any program updates should be installed with the standard installation procedure described here. The update should be installed to the same location as your previous version of HydroCAD. Program settings and user data files are not altered by the installation process.
HydroCAD can be removed by using Add/Remove programs on the Windows control panel. All user settings and data files are preserved during an uninstall. Only the original HydroCAD program and data files are removed.
Administrators' tip: You can perform a silent uninstall by using the "undeploy" program located in the HydroCAD program folder together with the /silent option. Note that all user settings and data files are preserved during an uninstall.
Whenever you install a different version or edition of HydroCAD, it will replace any edition already on your computer. However, all data and settings are preserved and are immediately available for use by whatever software was most recently installed.
For example, if you start with the HydroCAD Sampler and subsequently install a full program, the full program will replace the Sampler, retaining all your settings and data. This also applies to the trial, metered and express editions.
This means that you can only have one HydroCAD installation at any given time. If for some reason you need to switch back-and-forth between editions, it takes just a few seconds to run the desired setup program and make the switch.
Just install the earlier version to the same folder as your current installation. You do not need to uninstall your current program. (See details in previous section.)
HydroCAD must always be installed on the individual PC's where it will used. However, you may share your license(s) over a network subject to the terms of the License Agreement. For further details please read about license pooling.
There are several types of files that you may want to share between multiple HydroCAD installations. For project files, just place the file in a shared folder. Other files, such as custom rainfalls or chamber definitions, can be shared by placing them in the same folder as the project(s) that use them. No special setup is required, since HydroCAD always looks in the current project folder for these custom files. However, if you want to share data files that are used by projects in different folders, you can setup shared data files.
To increase your node capacity, start HydroCAD and enter your revised serial number on the Settings|Serial Number screen in place of the old number. Unless you are also installing a newer version of HydroCAD, you don't need to re-install the software - just enter the new serial number.

Earlier programs were normally installed in C:\HydroCAD, and are not altered as long as the new program is installed in C:\ProgramFiles\HydroCAD, as recommended by the setup program. Network users should also install to C:\ProgramFiles\HydroCAD, rather than to a network drive as recommended with earlier versions.
To import projects from HydroCAD-5 (or earlier), use Project|Import|HydroCAD-5 on the new HydroCAD menu. This will translate any existing project without altering the original files.
