DLL load failed: The specified procedure could not be found.
Hello,
I'm a IT support person we are getting this error in our virtual lab environment "DLL load failed: The specified procedure could not be found." more detailed error below. On physical computer I do not get this message. I checked few things like python installed few versions same result and updated vc++ redistributables.
Thank you,

Hi @huss203 ,
My main guess would be that your systems have multiple versions of some DLL that is used by SciPy, and that the wrong DLL is picked up, for example because the location of this other DLL comes before the location of the DLL that is bundled with OpenSesame. Could it be something along those lines?

Thank you Sebastiaan, I will try to pin point with the DLL., we do have lot of other applications running...
Thanks so much @romankris !
