Hello,

i am facing an issue where i find no adequate help in several online forums.

What i did so far is pretty simpel:  
Using PyCharm IDE  
Created Conda Python3.7 venv  
installed vtk package (8.2.0) via conda, which worked  
downloaded the cylinder example from [vtk.org](http://vtk.org) copypasted and just tried to run, getting the following error in a window:

What I tried:  
Checked my System for OpenGL version,  
which is version 3.1 according to OpenGl extensions viewer

Downloaded and built GLEW via CMake and VSC 2019, which worked as far as i can evaluate

Triedd looking for the file “vtkWin32OpenGLRenderWindow” via cmd Box and dir vtkWin32OpenGLRenderWindow /s /p which had no output.

So at that point i have no idea what to do. As i run an example from [vtk.org](http://vtk.org) the code is clearly not the problem, aswell as the vtk version downloaded via conda.

Does anyone have a suggestion, i cant be the only one having this error when running a vtk script in python

Regards
