I had difficulty in using the command to call knime.
I use knime to call a .bat to solve a problem.So I use two nodes to call this .bat,it's OK.
But if I use comment to call this knime project,there are two situations.
A:If my .bat is very easy. (e.g. notepad.exe) .It's OK.
B:If my .bat is a litte complex.
It occous an error(You can see it as follow picture):
My knime project:
Are there anyone can solve this problem?Thanks very much.
