Argos uses a dongle (hardware key) to control licensing of the program and the standard program cannot run without a dongle (see below).
The dongle uses the USB port. There are two types of usb dongles, a blue dongle for single-user license and a red dongle for a floating license. For the single-user license every user must have a dongle in her own computer. For the floating license only one dongle is required and that dongle can be installed on a local server. Please specify the type of license (dongle) you want when ordering Argos
®.
However, you may download the trial version of Argos
® here, which does not require a dongle.
