Software Protection

Eye4Software Hydromagic is protected against unauthorized use by an (USB) dongle, or by installing a software based, computer bound, license on the computer. Upon ordering or renting the full version of the software, either the dongle is shipped, or an activation link will be send by a separate e-mail. This depends on the license type ordered. The Hydromagic Dredging software will only be sold with an USB dongle.

Computer bound license

Since version 8.4 of the software, the software can also be activated with a so called 'computer bound license'. When the customer chooses a computer bound license instead of a physical dongle, an URL is generated for each computer the user is allowed to run the software on.

This license doesn't require any shipping, so delivery times are close to zero. It is not possible to transfer this kind of license from one computer to another. If you are planning to often replace or switch computers, we recommend that you go for a dongle license. For more information on how computer bound licenses work, please check this document.


Make sure the dongle is inserted in the USB socket correctly. On some dongle models two LED's (red and green) will lit up shortly on insertion. Please note that the newer dongles, which are made entirely out of metal, do not have LED's anymore. When you start the software, and the following error message is displayed, it means that no valid license has been found on the system. It will also be displayed when you try to run a Hydromagic version which is more recent then the expiration date of your support contract. In this case you can download an older version of the software from the "Download Archive".

Dongle troubleshooting

In some cases the software displays this error, even when the dongle has been inserted. Only in rare cases this is caused by a faulty dongle. When you encounter this error message while the dongle has been inserted, please perform the following steps first:

- Make sure the dongle has been inserted fully;

When the device isn't inserted correctly in the USB socket of the computer, the dongle isn't going to be recognized by Windows because it isn't powered properly.

- Try different USB sockets on your PC;

Some devices won't work with USB 3.0 sockets on your computer, trying another USB port might help. This check also rules out any defective or disconnected USB sockets on your computer.

- Make sure the CodeMeter runtime is installed;

The CodeMeter runtime is used by Windows and Hydromagic to access the dongle. When this piece of software is missing the dongle might not work. The CodeMeter runtime is installed during the Hydromagic installation. When for some reason installation is corrupt, you can reinstall it by reinstalling Hydromagic.

- Check whether the dongle shows up in the Windows explorer as an USB drive;

This is a good indication to see whether Windows has detected and installed the device driver software for the dongle. When the dongle doesn't show up you might try another computer. When the dongle shows up, but isn't recognized by the software, please request a license update.

- Make sure that no mouse driver has been installed on the USB port you are using;

In some cases when a NMEA0183 device has been connected to your Windows PC, it will be recognized as a "Ballpoint Mouse". This might block an USB port. Go to your computer's "Device Manager" and remove this device and see if the dongle is recognized.

- Temporarily disable any virus protection on your computer;

When a dongle is inserted, software will be loaded, for instance the "CodeMeter Server" which is used to communicate with the dongle. In some cases this might trigger a false positive in your virus scanner software, blocking the software from being started. When this does not help, please do not forget to re-enable your virus scanner software.

- Try the dongle on another PC.

After performing the above steps, it can be possible the dongle still isn't working. In this case, repeat the steps on another PC. If still not working, please contact support.
