HydroCAD® Stormwater Modeling - Since 1986
There are several ways to run HydroCAD:
The first time you run HydroCAD it will ask for your serial number or
If you have problems during the startup process, please review the following list of common startup issues.
If you purchased an increase in your node capacity, but HydroCAD still shows the old capacity, you need to enter the updated serial number, as provided with your order. Open the Settings|Serial Number screen and enter the new number in place of the old one.
Lost or Rejected Password
The Settings|Serial Number screen includes the option to set a user-defined password. We encourage the system administrator to set a password in order to prevent unauthorized changes to your license information. (This password is completely independent of any download password that may have been issued with your software.)
If your password is lost or forgotten, it cannot be recovered. However, you can reset your password by deleting the hydrocad.hcl file. The next time you run HydroCAD you will have to re-enter your serial number, and will have the opportunity to set a new password. Details here.
Shared serial numbers are not recognized
If you are sharing your license(s) over a network, all workstations must use the same drive letter or UNC name to access the license information. If the path isn't the same, other workstations will see an empty serial number form. For further details read about license pooling.
Missing Serial Number
If you previously entered your serial number, but HydroCAD is asking for it again, this indicates that the license file is not accessible. This can occur if the license file was deleted, damaged, or moved to a different location. To correct the problem, locate the original file or reenter the serial number. To avoid future problems under Windows Vista (or later), make sure you're using HydroCAD-10 or later. Details here.
Missing Project Files
If your HydroCAD project files appear to be missing, verify the folder where you stored the files. Although the default files are stored in HydroCAD\Projects, you are free to store files anywhere you choose. Searching for all *.HCP files will locate all HydroCAD projects on your computer.
Project files may also seem to "disappear" when using an older version of HydroCAD (9.1 or earlier) with a newer version of Windows (Vista or later). In these environments the user files normally stored in C:\ProgramFiles\HydroCAD\Projects are automatically redirected to a separate user-specific folder, causing the files to be inaccessible to any other "user". This means that running HydroCAD under a different account may cause the files to effectively "disappear". To avoid this situation, make sure you're using HydroCAD-10 (or later) which has been modified to store all user files in the proper locations. Details here.
"Network files not found"
This message indicates that HydroCAD was unable to find a network installation of HydroCAD, which is sometimes used to share rainfall tables and other data files. This feature is independent of the license sharing mechanism, as described above. It is used only in special cases in order to use a centralized copy of special lookup tables.
To eliminate this message, select Settings|Network on the HydroCAD menu and click the Reset Folder button. For further information about this feature, click the Help button on the same screen.
"Insufficient Access Rights"
This error has been known to occur if an anti-virus program is blocking access to the HydroCAD executable file. Right-click the HydroCAD.exe file for further details and options. There may also be an "Unblock" button in the file properties. If you still have problems, temporarily disable you antivirus product or contact your system administrator.
HydroCAD should not be run using Windows "compatibility mode". Running in compatibility mode can interfere with certain HydroCAD operations, including the ability to access external applications, such as AutoCAD.
HydroCAD Window(s) not Visible
If you previously used HydroCAD with a dual monitor setup, and you moved or removed one of the monitors, HydroCAD windows may open in an off-screen location, where they cannot be seen. To correct the problem, reset the window locations by using this registry patch.
"Your HydroCAD installation is incomplete"
This message will occur if the program files have been manually moved to a new folder or computer. To install HydroCAD, you must run the original setup program, either from the HydroCAD CD or from the download.
If the error still occurs after running setup, make sure HydroCAD is not configured to run in Windows "compatibility mode." To check these settings, right-click the HydroCAD shortcut and select "Properties". Then click the "Compatibility" tab and make sure none of the options are selected.
For HydroCAD 6.1, this message can also occur if you didn't have sufficient access rights when installing the program. Try re-installing the program with full administrator rights. (HydroCAD 7.0 and later will verify all access rights before allowing the installation to continue.)
"No default printer"
HydroCAD requires that a default printer be designated in the Windows printer folder. If you still get this error with a designated default printer, your default settings may be damaged. To correct the problem, set a different printer as the default and then re-designate the original printer.
"IntegrationSupport.dll is missing"
The metered and trial editions of HydroCAD use a special "Dashboard" to control program operation. If you get the message "The program can't start because IntegrationSupport.dll is missing from your computer", this indicates that the Dashboard was not properly installed. Run the HydroCAD setup program again, and make sure you allow the "Dashboard setup" to complete. If you prefer to run the Dashboard installer separately, you will find the file called "OnDemandSetup.exe" in your %temp% folder.
HydroCAD help pages will not open
Help links not working in HydroCAD-9 or later
Clicking a link in the HydroCAD help system will normally open that topic in the same help window. If the new topic tries to open in your web browser (instead of the help window), this indicates damage to the HTML help configuration on your PC. To correct the problem, open a command prompt and re-register the help system:
1) Select Start|Run and type
A padlock appears next to my HydroCAD project files
Prior to HydroCAD-10, the default project folder was located in ProgramFiles\HydroCAD. With the introduction of Windows Vista, access to ProgramFiles is restricted, which can cause a padlock icon to appear next to files in this folder. This is resolved in HydroCAD-10 by moving the default project folder to SharedDocuments/HydroCAD. Details here. To resolve the problem please update to the latest HydroCAD release.
Toolbar Buttons are blank
If the buttons on the HydroCAD toolbar are blank, you may need to update your Windows "common controls." You can download the update from Microsoft at www.microsoft.com/msdownload/ieplatform/ie/comctrlx86.asp Most customers should use the latest "x86" download listed on this page.
Blank toolbar buttons can also be caused by video card problems. This is usually corrected by installing a new video driver, which can be obtained from the video card manufacturer.
A few customers have reported problems with HydroCAD data stored on a Novell Network drive. The reported symptoms include:
These problems seem to originate in the Netware server and/or client software. This may be confirmed by moving your project files and/or license information to a non-Netware drive. For a permanent solution, please contact www.support.novell.com for assistance with your specific system configuration.
