Can you try a different version of Windows 7?

Can’t run experiments, got a ValueError: embedded null byte

Hello, I am very new to PsychoPy and get stuck at the very beginning. I’m trying to start with a simple “Hello World” but nothing happened after I click the Running button. I checked the output in the coder view and it shows a ValueError: embedded null byte. I have no idea what does it mean and what is the issue here. : ( [image] I’m using: Win 7 PsychoPy version:v 3.1.2 Thanks in advance Ran
