I have just moved from 4.2 to 4.3 (kepler). I was working on Eclipse RCP(OSGi framework) which was working fine with 4.2, but once i moved to Kepler- started getting below mentioned error while launching. Any kind of help is appreciated.
java.lang.RuntimeException: Application "org.eclipse.e4.ui.workbench.swt.E4Application" could not be found in the registry. The applications available are: org.eclipse.equinox.app.error.

Try this: open *.product file and then on dependencies tab check "Include optional dependencies when computing required libraries".
Make sure to use the default target:
Preferences -> Target Platform
And check the "Running Platform (Active)"
