Please note that If you are already using a version of EMF other than 2.0.1, you must uninstall it by deleting the folders that correspond to your existing EMF plug-in under your Eclipse plug-ins folder (For example, c:\starthis_demo\eclipse\plugins). The exact folder names cannot be provided here as it depends on the version of the EMF plug-in that you have installed on your machine.

Please remember that the Eclipse workbench must be restarted for the changes to take effect.

If you already have EMF version 2.0.1 installed, please skip this section and proceed to Chapter 3, Graphical Editing Framework (GEF) 3.0.1.
