I have configured vtk, qt and itk using VS 2017 on Windows. (VTK 8.2, Qt 5.14.1 )  
Now I want to try a very simple example with the Sphere [https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/Sphere/](https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/Sphere/) but I get the following error when I open the Sphere.exe file “The code execution cannot proceed because vtkInteractionStyle was not found”. The build was succeeded when I configured vtk.  
Any help is appreciated.

Hi @siaeleni - you need to be sure the vtk dll files are in your path when you launch the executable. There’s some more information, for example, here:

[http://vtk.1045678.n5.nabble.com/quot-vtkCommonCore-6-0-dll-is-missing-from-your-computer-quot-td5725609.html](http://vtk.1045678.n5.nabble.com/quot-vtkCommonCore-6-0-dll-is-missing-from-your-computer-quot-td5725609.html)

Note that for some apps, like 3D Slicer, there are utilities or scripts that set up the paths and launch visual studio pre-configured. If you do a lot of development on this app you may want to make a little batch script that similarly launches visual studio with the Path variable set as needed.
