Installation and Activation of HYDRUS 1.xx on a Single Computer

Here we assume that you have downloaded the latest installation program of HYDRUS 1.xx and extracted setup files to a temporary directory, for example C:\TMP\HYDRUS_Installation.

HYDRUS installation:

1. Run the HYDRUS installation program (setup.exe) located in the temporary directory with extracted setup files, for example C:\TMP\HYDRUS_Installation\Setup.exe.
2. The installation program will ask you for destination directories for the HYDRUS program files and data files (HYDRUS projects and settings). Remember that HYDRUS data files should be located in a directory that must be fully accessible by HYDRUS users for reading/writing/deleting HYDRUS project files and other files with HYDRUS settings.
3. Run HYDRUS 1.xx (double click on the icon installed on your desktop) and test to ensure that it works correctly. Without activation HYDRUS works as a demo version (calculation and saving of data are disabled), however you can look at the results of several examples included in the installation.

HYDRUS activation:

1. Please remember that HYDRUS activation requires administrator’s privileges, i.e. you must be logged as administrator (or as a user belonging to "administrators" group) when generating request codes and when entering activation codes. Under Windows Vista and Windows 7 you must run HYDRUS “As Administrator” (click on HYDRUS icon on your desktop by right mouse button and select “Run As Administrator”).
2. Run HYDRUS and go to the “HYDRUS License and Activation” dialog (see the picture below)
    
3. In the left combo-box select the HYDRUS Level you want to activate. The program will generate License Request Information involving two codes specific for your computer and the selected product.
4. Copy and save the generated license request information. Press the "Copy" button ("Copy to the clipboard" in older versions) which will copy request codes and the program version to the clipboard.
5. Open NOTEPAD (or another word-processing program) and paste request codes from the clipboard (press Ctrl + V). The pasted text should look like this:
   
   Hydrus version: 1.09
   Level to activate: 3D Standard
   Network License: No
   Request Code 1: 298032304
   Request Code 2: 118295067
    
6. Important: Check stability of your request codes. Close HYDRUS and open it again. Go to the HYDRUS License and Activation dialog and check displayed request codes. They must be the same as your previous codes displayed in the NOTEPAD. If your new request codes are different then there is a problem and you must inform us about that.
7. Send your request codes (the text in NOTEPAD) to your HYDRUS distributor by e-mail. Please, do not forget to add your HYDRUS license number or another information for finding your license in our database.
8. When you receive activation codes from your HYDRUS distributor run HYDRUS and enter received codes in the "HYDRUS License and Activation" dialog into fields "Key1" and "Key2" and press the button "Activate Now". Activation codes must be entered on the same computer and under the same user account that was used to generate request codes.
9. Remember that activation codes are hardware-dependent and will not work on other computers. You should deactivate HYDRUS before any hardware changes or reinstallation of the Windows operating system. To avoid problems, please, read thoroughly Important Remarks on HYDRUS Activation and Deactivation.
