MYSQL Drivers Un-Installed


When I installed the new version of KNIME (4.6.0), all the previous installed MYSQL drivers were un-installed. As a result, 90% of my KNIME workflows cannot be run, because I cannot connect to MYSQL.

Please help,


Hi Alex,
I’m sorry to hear that. If you did upgrade from an existing KNIME installation can you please restart it manually e.g. closing and starting again, instead of using the Restart functionality via the File menu. It seems that restarting KNIME does not uses the new settings that we added to the knime.ini file which unfortunately causes that the DB drivers are not loaded.
If you experience this problem with a fresh installation can you please post here the error messages from the KNINME log file which you can access from within KNIME via View->Open KNIME log.
