Can I install new JavaRuntime version on top of previous? Automatic (CLASS)PATH change?

Discussion in 'Java' started by Raymond Schanks, Feb 18, 2010.

  1. Can I install a new JRE on top of an existing JRE (in the same directory) on WinXP?

    Or do I have to uninstall the old JRE first?

    More important: Does the new JRE installation process change the PATH and CLASSPATH environment
    variables e.g. put the new PATH BEFORE all existing values?
