Installation and Activation of HYDRUS
Downloading the Installation Program
The installation program for the full version of HYDRUS is only avilable to customers who purchased a HYDRUS license. They will receive a password to their account on HYDRUS license server (ELIS) where they find the installation programs and other information needed to install and activate the software. We recommend you install and activate the latest version of HYDRUS.

Instructions for the Installation and Activation of HYDRUS
Stand-alone Computer
Network Installation
The network authorization of HYDRUS is controlled by NetHASP Hardware Key. HYDRUS should be installed on each computer, connected to the network, in the same way as on any other stand-alone computer (i.e. HYDRUS program files can be located on a local drive of the computer).
Remarks on Time-limited Activation
The activation of HYDRUS is always time-limited (even if you have a permanent license) and the maximum activation period is one year. You can prolong the activation any time before its expiration using the button "Extend activation on-line" in the HYDRUS license dialog. After the authorization expires, you can reactivate HYDRUS using the on-line activation or by e-mail (see "Installation and Activation" above). The time-limited activation was introduced to prevent some unwanted consequences in events such as computer crashes and similar hardware problems that require a new activation of HYDRUS without its prior deactivation.
Deactivation of HYDRUS
When you should deactivate HYDRUS
- Before any hardware changes (motherboard, hard-drives, graphic card, BIOS, etc.)
- Before reinstallation of Windows
- Before reformatting the hard-drive with HYDRUS
- Before changing the network path to HYDRUS (applies to the network installation)
- If you wish to move your license to another computer
- If you know that you will not be using HYDRUS for a long time
Deactivation - Common Instructions
- HYDRUS deactivation requires administrator’s privileges. Run HYDRUS “As Administrator”, i.e. click on the HYDRUS icon on your desktop using the right mouse button and select “Run As Administrator”.
- Open the HYDRUS License and Activation dialog (main menu -> help -> HYDRUS License and Activation) and press the “Deactivate on-line” or “Deactivate by E-mail” button. If your computer is connected to the internet, we recommend you the on-line deactivation.
On-line Deactivation
- Press the "Deactivate on-line" button.
- Enter the deactivation key (the same key which was used for HYDRUS activation). If you forgot this key, you can obtain it in ELIS.
- If you have a firewall, allow all internet connections in the popup window which may be displayed.
- HYDRUS will connect with our server and will be deactivated.
Deactivation by E-mail
- Press the ”Deactivate by E-mail” button, which will deactivate HYDRUS on your computer.
- HYDRUS will generate a special Deactivation Code, which serves as a proof of deactivation. This code will be displayed in the HYDRUS License and Activation dialog.
- Login to ELIS, go to Licenses and Workplaces, select the Workplace corresponding to the computer that you just deactivated and deactivate this Workplace using the Deactivation Code. This will unlock the WP and make it available for activation on another computer.
- You can also send the Deactivation Code to support@pc-progress.cz or to your HYDRUS reseller, who will unlock the deactivated workplace in ELIS instead of you.
Reinstallation or Moving License to Another Computer
HYDRUS Reinstallation
If you reinstall HYDRUS with the same version (or with a newer version) on an activated computer then the authorization remains active automatically, i.e., you need not deactivate HYDRUS before the reinstallation and ask for new activation codes. This applies to the single-user license on a standalone computer where HYDRUS was working as the full version. The same applies also to the network installation under the assumption that HYDRUS is reinstalled on the same network drive (with the same UNC path). In such a case please remember that the same version of HYDRUS should be installed on all network clients.
Moving HYDRUS license to another computer
Moving HYDRUS license to another computer is simple and you can do it yourself (without assistance of customer support) either on-line or in ELIS in two steps:
- Deactivate HYDRUS on the old computer (see instructions above).
- Activate HYDRUS on the new computer (see instructions above).
