Program Authorization
The term "Program" in the following text refers to a specific program, e.g. HYDRUS, DREAM Suite...
All Programs are secured against an unauthorized use by a hardware key (USB dongle - HASP) or software activation. The method of protection can be selected when ordering a user license. Both methods have some advantages and also disadvantages - see details below.
The authorization is verified when starting the Program. If any failure occurs, a warning is displayed that the program is running in a demo mode, in which the Program is not fully functional, i.e. it is not possible to run the calculation and/or the Program functionality restricted in another way.
Hardware key (USB dongle - HASP)
The hardware key is very simple to use and you can easily move the authorization from one computer to another one. You just need to insert this USB device into your computer and Program will find it automatically. A problem may occur if the hardware key is lost, which can mean the loss of the license.
Software activation
The software activation is a process when the authorization of Program is based on a unique numerical code, generated for a particular computer and for one-time use. The code is tied to the hardware configuration, i.e. it cannot be used on another computer, or reused on the same one if losing the authorization for some reason. Each activation is time-limited (even if you have a permanent license) and must be prolonged before (or after) its expiry. 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 Program without its prior deactivation. The Program can also be deactivated manually and the license transferred to another computer.
