Ple4Win Professional can only be used if an active security key (dongle) is connected to the computer. If the program has been bought, the security key  delivered is active permanently. In case of renting the system the key is activated for a certain period on request of the user. Activation and deactivation is done by sending context en update files via e-mail.
