What is a Release Candidate?

The term RELEASE CANDIDATE refers to a pre-release version of the software that is nearing the completion of a final product. The E-Prime v2.0 and E-Prime v2.0 Professional RELEASE CANDIDATES offer a number of new features and have undergone testing for quality and timing accuracy. Registered users will be able to freely download any additional modifications to the system up to and including the Final Release. Technical support will be provided to registered users via the common E-Prime Web Support interface.

E-Prime 2.0 Professional extends E-Prime v2.0 to offer enhanced capabilities for more sophisticated designs.

Yes. Experiments created using E-Prime 1.x will upgrade to E-Prime 2.0 without error or significant modifications. When an experiment is upgraded to E-Prime 2.0, it receives a new extension (.es2), and preserves the original E-Prime 1.x file so that you can continue to access the original (.es file) using E-Prime 1.x. Experiments upgraded to or created from scratch using E-Prime 2.0 (.es2 or ebs2 files) cannot be accessed or run using E-Prime 1.x.

Yes. E-Prime 2.0 will support what is known as a "side-by-side" installation where both E-Prime 1.x and E-Prime 2.0 can be on the system at the same time. Experiment files can easily be upgraded from E-Prime 1.x to E-Prime 2.0. Files converted to the E-Prime 2.0 format or created from scratch using E-Prime 2.0 (.es2 or .ebs2 files) cannot be accessed or run using the E-Prime 1.x system.

Can I continue to run my E-Prime 1.x experiments if I upgrade to E-Prime 2.0?

Yes. E-Prime 1.x and E-Prime 2.0 are separate systems. When experiment files are upgraded from E-Prime 1.x to E-Prime 2.0, the original experiment file is preserved with the .es extension, and the upgraded file receives a new extension (.es2). You may continue to run the original (.es) experiment file using your E-Prime 1.x system, or you can run the upgraded experiment file (.es2) with E-Prime 2.0. Files converted to the E-Prime 2.0 format or created from scratch using E-Prime 2.0 (.es2 or .ebs2 files) cannot be accessed or run using the E-Prime 1.x system.

Yes, if your colleagues are also running E-Prime 2.0. Files converted to the E-Prime 2.0 format or created from scratch using E-Prime 2.0 (.es2 or .ebs2 files) cannot be accessed or run using the E-Prime 1.x system. Please contact PST for information pertaining to our E-Prime Run-Time license as a low-cost solution for collaborators who have not yet upgraded to E-Prime 2.0.

You may locate your serial number in the About box in the Help menu in E-Studio or on the sleeve which holds the CD, located on the inside cover of the Getting Started Guide.

Although preliminary timing tests with E-Prime 2.0 Preview versions with the BBTK have resulted in expected timing values, thorough and formal timing results will not occur until later stages and final release of the E-Prime 2.0 system. Early versions of the E-Prime 2.0 BETA will notice significant delays when presenting movies. These delays will be logged accordingly via the FirstFrameTime available logging value. Subsequent releases of the E-Prime BETA will focus on movie playback timing. Because of the significant changes required to perform accurate movie playback, the display subsystem has not been modified in the initial releases of the E-Prime 2.0 BETA to ensure stability. Please keep posted to http://www.pstnet.com/products/e-prime/timing for both E-Prime 1.x and E-Prime 2.0 timing information.

Traditional Experiments will require at lease a 1GHZ processor and 256MB of system memory.

The cost of an E-Prime 2.0 Professional Network License is based on the number of concurrent seats purchased (10 seat minimum with quantity discounts applicable). The number of concurrent seats purchased corresponds to the number of copies of the E-Prime software that can be used on the network simultaneously for experiment design. For every 10 concurrent network seats purchased, users will additionally receive 2 complimentary E-Prime 2.0 Professional Single User Licenses (e.g. for travel or general use of the software when not connected to the local network.) Each site will receive one network license key which may be attached to any machine running on the local network via a USB port. All other machines on the network will check for the existence of this key when the E-Prime software is launched and will permit the launch to continue only if there are additional seats currently available.

The E-Prime 2.0 Professional Network system is identical to the E-Prime 2.0 Professional Single User system in regards to its capabilities and features. However, the network license offers lab administrators and IT personnel more efficient and centralized control of their E-Prime software license by supporting the �ghosting� of lab machines from a single software image. This process will allow sites to recognize significant cost and time savings when imaging, deploying, migrating, and managing systems.
