Hardware Key and Licenses
E-Prime 3.0 is a copy-protected system requiring a hardware key that connects to the computer’s USB port. The hardware key copy protection scheme limits the number of development machines to the number of licenses purchased. The hardware key is required for registration of E-Prime 3.0. Other applications require the hardware key to be installed depending on the type of license in use.
NOTE: Users should not experience any problems installing or using E-Prime 3.0 if the hardware key is correctly in place and the serial number was correctly entered. However, if the hardware key should fail, contact PST Product Service and Support immediately via http://www.pstnet.com/support.
Single User License
A Single User License allows the user to develop experiments on one computer at a time. The hardware key must be connected during registration of E-Prime 3.0, and while developing experiments within E-Studio. E-Studio will not load if the hardware key is not connected. With the Single User License, users may install E-Prime 3.0 on multiple machines, and simply move the hardware key to the machine to be used for experiment development. If more than one concurrent development station is necessary, additional Single User License must be purchased.
The Runtime application (E-Run) is not copy protected. E-Run may be installed on up to 25 machines within a single lab, and used for data collection on multiple machines simultaneously with a Runtime Only installation.
A Network License permits the development of E-Prime 3.0 experiments on multiple machines used concurrently within the licensed department, up to the number of purchased seats. The Network License requires the hardware key to be connected to a network machine and the network connection to be active during the registration and validation process, and while developing experiments within E-Studio.
