I am just starting to use KNIME. I have installed the Numeric Distances Workflow and tried to start working through it but I cannot even start because I get an error message stating the "Workflow contains missing nodes - Errors during load due to missing nodes (Single Selection Input QuickForm). Do you want to search and install the required extensions?"
When I click "Yes", another error pops up stating "No suitable extensions found - Could not find any extension(s) that provides the missing node(s)"
I am looking for suggestions on what to try next.
