E-Prime has a run-only version, (not dongled), useful for fieldwork. But the snag is you need to bring the data files back to a full version for E-Merge and E-DataAid (to get at the raw data). Also you need the full version to modify your program.
How easy is it to modify DirectRT programs, and to get at raw data?
Can I modify a program on a machine that does not have DirectRT installed, and then transfer the program to run it on a machine that does have DirectRT? Does every machine that runs DirectRT programs have to have a full license? Can I read data files on a machine that does not have DirectRT installed? Are they text files, or in a proprietary format?
