Could not load license data from server. Error: KNIME Webservices are not available

Thanks for confirming. Just to confirm, which method did you use to install the executor in the first place? Downloading the executor/analytics platform from Download | KNIME and pointing to the installation there?

If anything else crops up just ask here in the forum.

For completeness, I am posting a link to this topic which I assume is the one that has the answer.
