I am experiencing troubles with opening Knime after installing version 4.6.0 on my virtual machine.
I have tried all the three possibilities of installing Knime (zip/executable/installer).
In all three cases of the installation methods, the installation process completes without any errors or problems.
But when I open Knime after installation the following message pops up:
Does anyone recognize this message/error? And does anyone know how to solve this issue?
I am currently running Knime version 4.3.4 and this version has been installed in the same way on my virtual machine. It runs without any problems.
Open a command prompt (need instructions?), browse to the KNIME installation folder, then run this: c:\program files\<whatever-that-path-is->\plugins\org.knime.binary.jre.win32.x86_64_17.0.3<...>\jre\bin\java -version
Does that properly print the java version number?
(The error suggest that the java installation is invalid/corrupted/wrong and we should confirm it’s all in order).
You should not be required to do that. Java comes with the Analytics Platform (it’s located in that folder that we have cited a couple of times above, that is C:\Program Files\Knime_new\KNIME\plugins\org.knime.binary.jre.win32.x86_64_188.8.131.5220429\jre)
There is something wrong with that java “installation” (it’s not really an installation because it’s just a folder; it’s not registered with the Windows OS – and it doesn’t need to be).
What we should be doing is to confirm that this installation is not corrupted. Therefore, I suggested above that we run the java.exe -version in that installation.
You need to do this from a command prompt (like you did above) but you need to qualify the path to the java executable, otherwise the command prompt won’t be able to resolve the path to the executable (even if you have cd-ed into that folder – it’s some shell security thing).
So please open a command prompt, browse (using the cd command) into the folder above, then run:
