I found the additional text in the knime.ini and fixed it. But now I have another problem but only with a certain workflow. It throw me the error message which you can see in the added file.
The following return codes are defined:
0 upon successful execution
2 if parameters are wrong or missing
3 when an error occurs during loading a workflow
4 if an error during execution occurred
Your workflow is producing an error. You should be able to trace it from the log output.
