Where can I download E-Prime 1.2?
All downloads are available in E-Prime Web Support under the Downloads section.

Is there anything special to installing E-Prime 1.2?
You can install E-Prime 1.2 on a fresh system or upgrade from any previous version of E-Prime.
NOTE: On systems with security, you must be a Administrator or Power User. If you are a "guest" or do not have the security rights to install software, you will receive an error when trying to install.
End users will use the same serial number and hardware key shipped with their original order to access E-Prime 1.2.

Should I update to E-Prime 1.2?
Most labs should move to E-Prime 1.2 to obtain the latest updates to E-Prime.
There are cases where a lab should not. For example, continuing studies.
In addition, if you have an "E-Prime Extensions", interfacing with external equipment, or using a 3rd party PackageCall, you should contact that vendor to ensure you are using a compatible version of E-Prime and additional add-on software or hardware.

NOTICE TO INVIVO IFIS-SA/ELOQUENCE CUSTOMERS: Invivo has requested that PST post notice to all current and future IFIS-SA/Eloquence customers that E-Prime 1.2 is NOT compatible with IFIS 1.1 software and is NOT approved for use or installation on any IFIS-SA/Eloquence system. Installing E-Prime 1.2 on an IFIS-SA/Eloquence workstation will result in a failure to launch experiments from the IFIS System Manager Client application. Please contact info@invivocorp.com for further information.

Are E-Prime 1.1 files compatible with E-Prime 1.2?
Yes, experiment *.es and data *.edat files created in E-Prime 1.1 are backwards compatible with E-Prime 1.2 and vice versa. Any script additions introduced in E-Prime 1.0, 1.1, or 1.2 that break syntax compatability are noted in the KB.

I have E-Prime 1.0, what should I do?
There are no updates available for E-Prime 1.0. PST encourages users to upgrade to E-Prime 1.2 and then apply any updates available.

I have Windows 95, what should I do?
Microsoft retired Windows 95 in 2000. Therefore, all systems that have Windows 95 should upgrade to a newer operating system. If the machine currently running Windows 95 cannot upgrade to a newer operating system, then a brand new machine should be considered. Support for Windows 95 in E-Prime has been discontinued.
