I have Ubuntu 11.10 kernel 3.0.0-12-generic-pae and librxtx-java version 2.2pre2-8 installed. NOTE: I left the predefined folder name as C:Program FilesJavajre1.8.0_65 because otherwise after changing it to C:EntwicklungJDK1.8.65 there would have been no indication for you to know that the JRE is being installed In my defense, the installation process does not state explicitly that the JRE is being installed next and the installation, at least in this German version, doesn't warn that folders and files are going to be overwritten, which is an undesirable effect from my point of view. Unfortunately, the German installation process doesn't state anywhere that the JRE is being installed except in the folder name of the Zielorder view and that it's installed in the base folder structure. The JRE aka its alias Java, which a mindful reader should have noticed, but I obviously missed twice, was installed in the same location overwriting the bin folder of the JDK with the bin folder of the JRE, deleting all files.Īn unneeded mistake on my side. In C:EntwicklungJDK1.8.65 there was a bin folder of the JDK installation I chose the folder C:EntwicklungJDK1.8.65 again this leads to the following conflict In this view, the installation process is asking in which folder I want to install Java after rechecking every letter of the installation process.ĭuring installation, the installer asks you where you want to install the JDKĪ progress bar is displayed and installation continues I was able to solve the "problem" myself.
