HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment\1.3.1 HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment\1.3 More registry keys are created using this scheme: (e.g.) If you're running applets from the browser, or possibly also Java Web Start applications (they look like applications insofar as they have their own window, but you start them from the browser), the choice of JRE is determined by a set of registry settings: Key: HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment
You can of course override the PATH setting or even do without it by explicitly stating the path to java.exe / javaw.exe in your command line or shortcut definition. This is usually a pretty elderly version of Java: 1.3, maybe? You'll want to do java -version in a command window to check that you're not running some antiquated version of Java. However, I've found some "out of the box" Windows installations to (also?) have copies of java.exe and javaw.exe in C:\winnt\system32 (NT and 2000) or C:\windows\system (Windows 95, 98). exes are below directories like C:\Program Files\JavaSoft\JRE\x.y.z. If you installed a JRE or JDK, the likely places to find the. jar files and started with java -jar xxx.jar or via a shortcut that does the same, the JRE that will be launched will be the first one found on the PATH. programs that are delivered (usually) as.
