E-Prime User’s Guide
Chapter 1: Introduction

1.4.1 Single User / Multi-Pack License
A single user license allows the user to develop experiments on one computer at a time. The
hardware key must be connected during installation of E-Prime, and while developing
experiments within E-Studio. E-Studio will not load if the hardware key is not connected.
However, the run-time application (E-Run) is not copy protected. E-Run may be installed on any
number of machines within a single lab, and used for data collection on multiple machines
simultaneously.
With the single user license, users may install E-Prime on multiple machines, and simply move
the hardware key to the machine to be used for experiment development. If more than one
development station is necessary, additional licenses must be purchased. When multiple single
user licenses are purchased (Multi-Pack License), each license is shipped with its own hardware
key.
1.4.2 Site License
A site license permits an unlimited number of E-Prime installs within the licensed department.
The site license requires the hardware key to be connected only during installation. The site
license does not require the hardware key for the use of E-Studio.
1.5 What to Know Before Reading This
Manual
Before reading this manual, a user should have a basic knowledge about operating personal
computers and experimental research design and analysis. A working knowledge of Windows is
essential, and at least one undergraduate course in experimental research methods is
recommended. The understanding of terms such as “independent variables” and “random
sampling” will be assumed. If this background is missing, it is recommended that the user first go
through a basic text describing how to use the Windows operating system and an undergraduate
text on experimental research methods. Furthermore, this text assumes the experience of
working through the Getting Started Guide accompanying the E-Prime CD.
1.6 Useful Information
1.6.1 How to abort an experiment early
Press Ctrl+Alt+Shift to terminate the E-Run application. A dialog box will appear confirming the
decision to abort the experiment. Click OK. The E-Run application will terminate. Within the E-
Studio application, an error dialog will appear displaying the “Experiment terminated by user”
message.
1.6.2 What to do if the hardware key fails
Users should not experience any problems installing or using E-Prime if the hardware key is
correctly in place, and the serial number was correctly entered. However, if the hardware key
should fail, contact PST immediately (see Technical Support below).
1.6.3 Locating the serial number
The serial number is located on the CD sleeve containing the E-Prime CD, inside the cover of the
Getting Started Guide. Place the serial number in an appropriate place so that it is readily
