When double clicking an .ebs2 file on a system that has more than one edition of E-Prime (Suite, Subject Station, Run-Time), E-Run will show a dialog that indicates which version of E-Run should run the experiment.
When there is a direct match, for example 126.96.36.199 generated .ebs2 on a system that has 188.8.131.52 then no prompt will occur and the experiment will automatically run.
It is recommended to use the version of E-Run in which the experiment was generated (for continuing studies). When this is not possible to match the runtime, the E-Run resolver dialog will indicate which version is preferred. In general, the resolver dialog will suggest a runtime that is later/newer than the ebs2 file. For example, if the .ebs2 file was generated in 184.108.40.206 but only 220.127.116.11 and 18.104.22.168 are on your system, the resolver will suggest 22.214.171.124.
If you choose a runtime that cannot handle the .ebs2 file, the E-Run dialog will indicate the failure condition.
To assist with matching the .ebs2 to the runtime available, regenerate the es2 file to ebs2 in the appropriate matched version.
In general, installing an older Subject Station on a machine with a newer Subject Station will not affect the resolver associations.
The exception to this case would be if the system is E-Prime 126.96.36.199 or prior or performing a repair on any installation.
When this occurs double clicking on an ebs2 may not resolve properly. To remedy this situation, open the newest E-Run from the Start Menu. When doing so it will detect if the ebs2 file association is correct and prompt to update if there are any issues.
