I installed the KNIME Expressions extension and now all of a sudden, KNIME does not start anymore. It shows the splash screen for minutes (we’re talking like 30+ minutes), no extension icons are loaded in the splash screen and the application itself does not open anymore.
Any idea how to overcome this?
What I have done already: Secured my workspace and deleted also the .metadata folder in the workspace.
Thank you in advance.
I had that issue several times recently, it seems to happen with newer KNIME versions – in my case, the KNIME application eventually always opened after waiting really, reaaaaaaaaaaaaaally long. Once it was a matter of approx. 15 minutes, once it literally took “a lunch break”. In any case, just waiting seemed to help, and the following restarts were back to normal pace.
I don’t know what’s going on behind the curtains, not to mention any cure, but I can confirm that it happened after installing or updating extensions.
This can happen when you have incompatible extensions installed together. Can you tell me which version of KNIME AP you are using?
So I basically uninstalled and re-installed now 4.6.3 (the problematic one was 4.6.2 and the extension I wanted to install was the KNIME Expressions - containing the Column Expressions Node).
Now I have SE Nodes (@qqilihq ), Vernalis, Palladian, KNIME Reporting (BIRT) installed and all works again.
@qqilihq Eventually I have to wait a little bit longer in the future, some say, I am to hectic
