Missing Function Exception error

[Vml_Burmester]

Does anyone have an idea what is going wrong here? This error appears when I run the experiment

File “C:\Program Files (x86)\PsychoPy3\lib\site-packages\pyglet\gl\lib.py”, line 63, in MissingFunction
raise MissingFunctionException(name, requires, suggestions)
pyglet.gl.lib.MissingFunctionException: glActiveTextureARB is not exported by the available OpenGL driver.

Hi,

This thread may give you some insight (and a possible solution).

OpenGL drivers error

I think Intel has some sort of agreement with Microsoft to ship drivers over Windows update now. So if your graphics adapter is discontinued (it is), it will likely default to using a generic driver and the OpenGL library which ships with Windows. However, I’m not 100% sure this is the case. The Windows OpenGL library can’t export features beyond version 1.4 of the OpenGL spec … and you need a minimum of 2.0 for PsychoPy. It’s entirely possible that the last driver is unsupported on newer Windo…

Best wishes,

Wakefield
