Hello, I have installed VTK 8.2.0 with Qt 5.12.5(with msvc2017 for 64 bit). I have also copied QVTKWidgetPlugin.dll from VTK directory to Qt plugins folder. But still there is no QVTKWidget in Qt creator application. Could anyone please give solution to me?

Many things can go wrong, but probably the most common is that release-mode designer.exe can only use Qt widget plugins dlls that are built in release mode.

I’d strongly recommend just using [promoted widgets](https://doc.qt.io/archives/qt-5.10/designer-using-custom-widgets.html) in designer to promote a `QWidget` to `QVTKWidget`. That way you won’t have to bother with the `QVTKWidgetPlugin`.
