I installed the JChem Extensions 2.8.2.v0204 in Knime 2.9.2 and pointed to my academic license in the Knime preferences. However i still get the error message "Configure failed (LicenseInvalidException): Node doesn't have the license key." when i try to use for example the pKa node from the calculator plugins.
I dont know if i have to do something else with the license.cxl file but so far i just copied it to the chemaxon folder in the user directory (C:/Users/.../chemaxon).
I would appreciate any help to solve this issue.
Thanks
Alex
