The SP2 update includes limited modifications that impact the runtime application (E-Run).
These exceptions will be encountered rarely, and are detailed at the end of this article. There are two minor exceptions whereby upgrading to SP2 may require an additional step to maintain full compatibility with the E-Studio file. es2 files created with E-Studio SP2 can be loaded, edited, and run from the SP1 version of the E-Studio application. Further, since SP2 is backwards compatible with SP1.
es2 files created in SP1 can be loaded, edited, and run from within E-Studio SP2. The SP2 update does not introduce an experiment specification file format change from E-Prime 2.0 SP1. We are able to maintain compatibility between SP1 and SP2 due to the nature of the bug fixes, which are concentrated on minor issues in the E-Studio application, and therefore users can update while in the midst of data collection, if desired. With these prior releases, PST recommended that users in the midst of data collection or longitudinal studies wait until the current study is completed prior to upgrade. The compatibility of SP2 and SP1 is in contrast to some prior releases, which often either introduced a file format change and/or included changes that might significantly impact timing. SP2 is compatible with SP1, and therefore users are encouraged to upgrade from SP1 to SP2 as soon as possible. It also provides several fixes to minor E-Studio bugs that have been found in prior versions of E-Prime. This service pack introduces improved stability in E-Studio by decreasing the occurrences of crashes and reducing HASP driver issues. E-Prime 2.0 Service Pack 2 (SP2) is now available.
