Hello. I tried to upgrade from 4.7.8 to 5.2.5, but it was unsuccessful, because the extensions could not be installed. Unfortunately, 4.7.8 was uninstalled before 5.2.5. I tried to use recovery from Windows, but it would not help, because Knime had not started at all. I would like to install 4.7.8, but I encountered this problem:
I pressed yes, but there was another message:
In the end, how to uninstall it and install. And I am also afraid that I lost all my workspaces.
The workspaces should reside in another location so you can change your KNIME software all you want. Having said that backup is always a good strategy.

The good strategy would be not to uninstall version automatically 4. before 5 if there are any incompatibilities between them. I coudn’t image that this cause so much trouble! I even cannot install the same version now.
Great thanks, I could recover manually through the control panel. At least the basic functionality is recoverable and the workflow is still available.
