Runner error when opening list file

Hi – I’m very new to PsychoPy and trying to figure out how to use Runner when collecting data. I created a list of 3 experiments that works fine on the computer it was created. However, when I open that list file on another computer which has the same version of PsychoPy installed and a folder with the necessary program files in the same location (i.e., within a folder on the desktop), I get the error shown below. (The Runner works fine if I create a new list file on the 2nd computer with the same experiments; so I can work around the issue, but as ultimately we’ll need to be able to run the same lists of experiments on 10 computers, I’m hoping that I can simply download copies of the list files on each computer.) Thank you.
