Psychopy installation V 1.85.1


Hey guys,

I’m installing psychopy on a series of lab computers in my department. I’m currently doing a test run just to see if it will work (Windows 7) so I can run a series of tests.

Unfortunately I am getting an error message when I run a practice experiment (builder view: one text stim and keyboard response).

Any fix suggestions would be greatly appreciated.

The error message is attached below.

Try updating your graphics card drivers. Google has many additional suggestions for you:

but updating graphics card is usually the key


Thanks Jon,

I will give that a run in the morning and reply.



Ok, So the lab computers are running with an old Intel G41 chipset , the drivers are unavailable from the Intel website.

Looks like a case of old hardware.

Thanks for the reply Jon.



These don’t work?


I’ve also used the intel update assistant.

Nope, when I go to install the appropriate driver from the link above I get an error/feedback message : “The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer. Setup will exit.”

With the latest driver update I get an error message: “This computer does not meet the minimum requirements for installing the software.”

Then I go to the manufacturers website (The PC model is a HP 500b Microtower), to get the driver update and when I install I get the same error message as above.

PC may just be a bit too old?
