Click on the details button and copy/paste the stack trace here. Also, go into the error log and paste any relevant errors: Window -> Show view -> Other -> Error log.

OK. That error message indicates that something went wrong earlier in the startup. Can you look at your error log as described above?

Well, I don't know what is wrong, but it looks like your installation is somehow broken. I'd recommend deleting your existing install of Eclipse and unzipping a new one.
