JRE are the runtime JVM invokers. There is a JRE in the JDK. Did you read the information on the *Oracle* website? Read that first, and understand it, before you start to rely on third-party sites like mindprod. > I have no entry in startup or a desktop pointer icon - result STUCK. > > Where do I go from here to get started please? Uninstall the ones you installed. Re-install the 64-bit JDK. You shouldn't need to do anything special with the PATH for a Windows installation. The Java installation doesn't include anything in startup, and really, why should it? It doesn't create any desktop icons, either. You can create an association in Windows between JAR files and the "javaw" JRE invoker, but for development you use command-line tools (like direct invocation of the "javac" command or Ant) or an IDE (Integrated Development Environment) like NetBeans or Eclipse. As explained in Oracle's Java tutorials. You *are* studying the tutorials, aren't you? RTFM. -- Lew
