**NOTE: This is not the latest version of E-Prime 2.0.
Welcome to E-Prime 18.104.22.168
E-Prime 2.0 Development has implemented a number of features that will require end users to upgrade their experiment(.es2) files. The resulting files will not be backwards compatible with previous editions of E-Prime. Because PST strives to avoid making changes to file formats in this way, the E-Prime Development Team has chosen to roll out all of the changes that affect file format into one release to avoid end users repeatedly having to upgrade their .es2 files, as well as to minimize problems with multiple file formats and collaboration between labs.
E-Prime 22.214.171.124 can be downloaded via the PST Product Service and Support site by logging into your account here. Professional and/or Standard will be available according to the serial number(s) registered with your account. If you have not yet created an account, you can create one using the valid serial number associated with your PST product by clicking here.
Is E-Prime 126.96.36.199 the Production/Gold release?
Yes, the release of 188.8.131.52 should be considered feature complete. It is currently in production and is no longer in Release Candidate stage.
NOTE: Do not update to E-Prime 184.108.40.206 at this time if you:
- Are collaborating with other sites using a different version of E-Prime 2.0
- Are scheduled to collect additional subject data for a continuing study
- Plan to analyze subject data in comparison to previous sessions
- Are using E-Prime 2.0 with any of the following extensions. All E-Prime experiments using any extensions except for E-Prime Extensions for IFIS should be using E-Prime 220.127.116.11a until further notice. E-Prime Extensions for IFIS users should continue to use E-Prime 1.1 SP3.
- E-Prime Extensions for Net Station
- E-Prime Extensions for Tobii
- E-Prime Extensions for Smart Eye
- E-Prime Extensions for fMRI
- E-Prime Extensions for IFIS

Additional Upgrade Questions:
Can E-Prime 1.x and E-Prime 2.x be installed at the same time?
Yes, but ensure that E-Prime 2.x is installed/updated after E-Prime 1.x. Any update to E-Prime 1.x can cause issues with E-Prime 2.x. After installing E-Prime 2.x, E-Prime 1.x may need to be opened as an administrator once before it is fully functional. Right-click on E-Studio 1.x and select "Run as Administrator" to complete the process.
Can E-Prime 2.0.8.x and E-Prime 2.0.10.x be installed at the same time?
No, only major version installations can be installed at the same time. However, multiple versions of the E-Prime 2.0 Subject Station installation can coexist on the same lab machine. KB5325 - FEATURE: Suite, Subject Station, and Run-Time detect other installations on machine (multiple Subject Station versions allowed)
Is it possible to uninstall 2.0.10.x and re-install 2.0.8.x?
If you have chosen to go back to E-Prime 22.214.171.124, it may indicate that a newer HASP driver is installed and then cancel the installation. Use 126.96.36.199a to overcome an issue with the HASP driver not permitting installation on a system with a newer driver.
KB4998 - FEATURE: 188.8.131.52a
Is there anything recommended to prepare my machine for E-Prime 184.108.40.206?

Legacy End User Comments
|Is it still recommended that I not upgrade to 22.214.171.124 from 2.0.8.x if we continue to run tasks that were created in 2.0.8.x on new subjects? We are collaborating with a different lab on a new task and cannot run a file on our system because it was created in a newer version of E-prime, so we would like to upgrade at this time if it is not recommended not to.|
|If you are starting a new study you can upgrade a more recent version. If you need to run an older study while working on a new study you can use the older version "subject station" installation. Contact PS&S or view the download links for that information.|
