Slime UML 2 runs on Eclipse 3.0 and higher; if you use an older version, check for old Slime UML versions.

To run Slime UML you must have GEF 3.1.1 installed. Please install it from the Eclipse Tools Site.

The first step after installing Slime UML should be to verify the correct installation.

• Stop all running Eclipse / Websphere Studio Application Developer instances
• Start the Instance where you installed Slime UML
• Open the New Wizard Page (File --> New --> Other)

There should be an entry "Slime UML Diagram" as described above.
