The experiment run well on other computers, but my laptop cannot run it. I re-install psychopy several times, but the same problem still show. Please help. Thanks!

I don’t know. I haven’t seen that error before. Could you tell us more about the laptop, particularly about the keyboard settings (How old is the device? Is this an unusual locale? is there a USB keyboard connected or is this the built-in keyboard? Anything else that’s different about this machine?)
