I have a sqldeveloper intallation on windows 7. When I started it up for first time it asked me to point to a java.exe. Well I think I pointed it to the wrong one because now when I go to start it up I get the message "unable to find java virtual machine" How do I change it to point to a different java.exe. There are many java.exe. How do I know which is the right one?. The one that it wants. How do I get this prompt back so I can tell it to point to the right one?.
