How to use AlfalfaPro
AlfalfaPro is a multiplatform application. You can run the program on either
a PC running Vista or earlier as well as a Mac running version 10.5.8 or earlier. To open
the files, double click on "AlfalfaPro.zip" file, and extract the files using WinZip, Stuffit (free at http://www.stuffit.com/win/expander/index.html
), windows extraction software or similar extraction programs. At the beginning of the extraction
you will be prompted for the encryption password which was given to you in class. The program will,
upon extraction, create a folder that contains AlfalfaPro.exe (executable jar file) and three other
files which are part of the program.
To start AlfalfaPro, double click on the AlfalfaPro exe file. The program will open in a new
window. Please click on "start a new test" to begin.
