 <p>You have to answer twice, about where to install Java. If you want to use your own directories, instead of Windows's, you have to set a separate directory for the JRE, which is what it wants to know, on the second ask. ORACLE's installer should have been done a little less ambiguously.</p> <p>If you try and answer the same directory, for the jre, as for the jdk, you won't have your jar.exe, or your src.zip folder. They are installed there, until it asks for the destination for the JRE. It might overwrite (remove all) the files in the root directory of the jre folder. In other words, that's the JRE1.8.0_102's bin folder in the root folder of your JDK, now, thanks to the installer.</p>
