Transfer experiment from Mac to Windows

Dear all,

I succesfully created a n-back on my Mac (psychopy version 3.2.4). However, when I try to open the experiment on my Windows pc (I need to use this task in my job that doesnt have mac) (psychopy version 2020.2.3) It stops after I type in the participant number and I get the following error (see below). I am not sure what to make of this…

Does any of you have an idea?

Best regards, Sanne

Dear Sanne,

Could you explain how to solve this problem ?

Thanks a lot,

there was no problem after all because I tried to load an old version on the windows that also had problems on my mac!
