Hi @dieter.lutz
It looks like something went wrong during the update, take a look at the tip in this post, it should fix it for you:

Lost KNIME Explorer when upgrading to 3.6

Hi, a possible fix is to run KNIME via your terminal using “-clean” as a parameter. open your command prompt/terminal navigate to your KNIME installation Windows: run “knime -clean” (without the quotes) Linux/MacOS run “./knime -clean” (without the quotes) If anybody encounters that problem it would be nice to mention that in this thread so we can narrow it down. If this doesn’t help you, please let us know. Cheers, Moritz

best,
Gabriel

Hi Gabriel,

the “-clean” commandline-Option fixed this issue.

Thanks !

P.S.: I´d just like to add, that this problem occured twice on my computer.
I tried the ZIp-Installation and Win-Installer.

Hi Gabriel -
My problem is a bit more complicated. It appears that when I installed the extensions for Schrodinger it installs another copy of Knime in a separate directory. When I fire up my original copy of Knime it works fine. The version in my Schrodinger directory has the error message in the explorer window. Running the knime executable with the clean command parameter within the Schrodinger directory or my original directory does not fix the problem. I get a warning when trying to update Knime or add extensions to the Schrodinger version. I did not do this. Anyone else having this problem?
Thanks, Brad

Updated: The “knime -clean” command did not work when both versions were installed but it did work when I removed one. Problem solved.
