Even with the help of others, installing a working version of the Eclipse Modeling Tools can be extraordinarily frustrating. Indigo (the most recent version of Eclipse) has been released. Avoid it as it doesn't work correctly with the tools that we will use. Also, I'm running on a 64-bit architecture machine. Don't download the 64-bit version of Eclipse; stay with the 32-bit, as the 64-bit version doesn't work correctly with the tools that we will use. Someday, this will be simpler. There is a series of installations that you will need. So here we go:
These tools provides a model-driven approach to generating graphical editors in Eclipse.

This install add OCL expression editors and OCL constraints to model declarations.
Help->Install Modeling Components->OCL Tools
Eugenia tools simplify the development of GMF editors.
