Then it is necessary to activate a new license in your HASP only once, according to point C. It may also happen that you have already had a HYDRUS license with HASP and you have purchased its upgrade. You will be informed about this fact in advance by our customer support and then you can follow point B. However, under certain circumstances, you can receive HASP which requires a one-time activation. Then it is necessary to install HYDRUS according to point A below. When purchasing a new HYDRUS license with HASP, the customer usually receives a fully functional HASP by post. The use of HASP eliminates these problems. The network installation using a software key (activation) is somewhat more complicated and some network administrators have complained about its lack of flexibility.
The program (e.g., HYDRUS) can be used on multiple computers (e.g., desktop and laptop) only by transferring a small USB key.The hardware key (dongle) gives users assurance that the program can be easily installed and used, for example, on a new computer.
Under certain circumstances, the activation code may not be immediately available and users have to wait till they get it (e.g., activation by e-mail). Activation of the program brings some disadvantages, such as that the program can be activated only on the allowed number of computers and the activation is always time-limited (up to 1 year) and needs to be repeatedly renewed.
Hardware keys are very effective copy protection devices, because they cannot be duplicated by the user. Upon startup, the application looks for the key and will run only if the key contains the appropriate code.
A Hardware Key (HASP), also called a "dongle", is a software copy protection device that plugs into the USB port of the computer.
