Could not initialize Chrome driver

Hi, I have a problem when running basic examples ’ Visualization of Sales Data’. I could not see any output.

Hi @plains and welcome to the forum.

Can you take a look at the post below? Changing browsers in your KNIME preferences may help - it may also be an antivirus or corporate policy issue.

Cannot use Scatter Plot: Chrome driver was not initialized Problem

Hi @cseozlem and welcome to the forum. Sorry for the trouble. Can you verify that you’ve disabled any antivirus programs, and tried switching to alternate browsers as shown in your screenshot above? If neither of those work, is it possible that you’re on a corporate laptop with Windows policies that would prevent launching background processes?

@plains

browser can be configured in Preferences → K

Hey ScottF, thanks for your reply. I have tried each brower in the preference but they didn’t work.It seems the background app running was enabled. Is there any other methods to visualize the results?

You could also try the older Scatter Plot (JFreeChart) or Scatter Plot (local) nodes as well.
