ERROR External Tool 4:999:789:779 Execute failed: Execution failed (exit code -1073741819)

While, I am trying to execute the external tool node in Knime, then “ERROR External Tool 4:999:789:779 Execute failed: Execution failed (exit code -1073741819)” is shown. Can you please help me resolve this issue?

Hi @anweshadas ,

welcome to KNIME Forum! By the sounds of the error, your external application may have terminated with said exit code.

Maybe you can provide some additional information so that others can help you further here.
We have put together a guide here:

Kind regards

Hi, thank you so much for your reply. So, basically, with the help of the external node of Knime, I was trying to run a Perl command. It is for a 5-fold cross validation. In folds 2, 4, and 5 it ran and executed absolutely fine. But, in the folds 1 and 3, it didn’t execute. Can you please tell me how to fix it?

With the information given I don’t know that we can be much help. It sounds likely that the error given is from the Perl side rather than the KNIME side. I would encourage you to run each fold manually from the command line and see what errors are generated by your external application on folds 1 and 3.
