Versions and Editions - The Basics
- What is an E-Prime version?
A version of E-Prime is a publically available build of the system that contains any combination of new features, extended functionality of existing features, enhanced documentation, and bug fixes. An E-Prime version is identified by its full version number and optionally by a version name. E-Prime version numbers are in the format of a series of 4 numbers separated by the "." character, e.g. E-Prime 188.8.131.523. Each number represented by an x must be the same for the version to be considered the same. For example, E-Prime 184.108.40.206 and E-Prime 220.127.116.11 are not considered to be the same version because the last number is different.
The first two numbers are referred to as the major and minor version number. When appropriate, we only refer to the major and minor version numbers; in such cases, any reference to the major.minor values covers all versions that share the same major.minor version number. For example, all of the E-Prime versions with a major.minor values less than 2.0 obtain low sound latencies with a combination of DirectX Sound and Windows XP, but not with DirectX Sound and Vista or Windows 7. Therefore, when documenting the recommended operating system and sound API combinations in INFO: Sound Latency - Windows Vista / Windows 7 (and beyond)  , we refer to 1.0, 1.1, and 1.2.
- What version of E-Prime am I using?
You can determine which version of E-Prime you are using by checking the About E-Studio box or reviewing the Program information from the Control Panel. For details, see the KB article INFO: How to Determine Version Number of E-Prime or Components of E-Prime? .
- What is an E-Prime edition?
The E-Prime 2.0 release introduced two different editions, Standard and Professional. Both are fully functioning versions, with the Professional edition offering enhanced functionality. For details on the differences between the Standard and Professional editions, see E-Prime Compare Editions.
- What edition of E-Prime am I using?
The E-Prime edition is identified in the Programs and Features Tool in the Windows Control Panel. (See INFO: How to Determine Version Number of E-Prime or Components of E-Prime?  for details on accessing the Programs and Features Tool, or check your Microsoft documentation.) When the Professional Edition is installed, "E-Prime Professional ()" appears in the name column; when the Standard Edition is installed, "E-Prime ()" appears. For example, the Professional edition of E-Prime Service Pack 1 version 18.104.22.1683 appears in the Programs and Features tool as follows:
In addition, the E-Studio application identifies the Professional edition by displaying "E-Studio Professional" after the experiment name in the title bar. The following illustrates the E-Studio title bar when the BasicRT sample experiment is loaded into the Professional edition:
Conversely, if you are running the Standard edition, the title bar lists only the experiment name and "E-Studio", as follows:
Updating, Upgrading and Downloading Versions
- How do I know when a new version of E-Prime is available?
New versions of E-Prime, both updates and upgrades, are announced in PST's quarterly newsletter. All registered users receive the newsletter via email. Also, new version announcements are included in the Downloads area of the user support site. (If you have not registered your system, you may do so at any time from the support site.)
- What is an update to E-Prime?
An update is any new version which shares the same major number as the version number of your original purchase. Updates typically contain a limited number of new features and/or bug fixes. For example, E-Prime 2.0 SP1 (22.214.171.1243) is an update for someone who purchased E-Prime 2.0 Production Release (126.96.36.199), because both versions have the same major version number (2).
- What is an upgrade to E-Prime?
An upgrade is any new version which has a higher major number as the version number of your original purchase. An upgrade typically contains a significant number of new features, enhanced functionality, and bug fixes. For example, E-Prime 2.0 SP1 (188.8.131.523) is an upgrade for someone who purchased E-Prime 1.2, because the major version number is different (2 versus 1).
- What does it cost to update or upgrade?
Updates to an existing system are included as a part of the web support plan for your product. If your web support has expired, a renewal may be purchased during that product's life cycle. Upgrades to an existing system must be purchased and are typically offered at a discount over the price of purchasing a new system.
- Will I need to purchase a new key if I update or upgrade?
The green E-Prime 2.0 USB Hasp key works for all versions of E-Prime 2.0. The purple E-Prime 1.x USB Hasp key works for all versions of E-Prime 1.x. If you are updating, you do not need a new key. If you are upgrading, you will receive a new key as part of your purchase.

More questions about editions
- How can I tell if my es2 file is a Standard or Professional edition experiment?
To determine if an es2 file is a Professional or Standard edition E-Prime file, open it in E-Studio.
- If you are running the Standard edition, you may only open Standard edition files. If you attempt to open a Professional edition experiment in the Standard edition of E-Prime, an error message appears.
- If you are running the Professional edition of E-Prime, you may open either Professional or Standard edition files. When an es2 file is opened in E-Studio, the word "STANDARD" or "PROFESSIONAL" appears next to the root Experiment Object name. This indicates if the es2 file is in the Standard or Professional edition.

- Can I edit a Standard edition experiment in the Professional edition?
A Standard edition experiment can be loaded into the Professional edition. When you select a Standard edition es2 file to be opened in E-Studio, the professional conversation prompt appears:
You have the option to either maintain the Standard file format or convert the es2 file the Professional version. Note that once you convert to the Professional file format, you can NOT switch back to the Standard file format. If this prompt does not appear or if you wish to create a default setting for opening experiments of different editions and disable the prompt, go to Tools, then Options, and adjust the settings in the E-Prime 2.0 Professional Conversion section.
- Can I edit a Professional edition experiment in the Standard edition?
No, an experiment in the Professional edition file format can not be loaded into the Standard edition.
- Can I save Professional edition experiment into a Standard edition es2 file?
No, an experiment that is in the Professional edition file format can not be saved as a Standard edition file from within E-Studio. However, a Professional edition user can make a Standard edition version of the experiment by opening two E-Prime sessions and cutting and pasting the experiment objects. The Experiment Object Properties must also be transferred. To check these, double click on the purple Experiment Object at the top of the Structure window and review the settings in each tab. Also, check for any User script by going to View, selecting Script, and clicking on the User tab. If there is script there and it is not copied to the Standard experiment, the Standard experiment will not compile. Always run the Standard experiment at least once to ensure that it works.
