I have downloaded Qt opensource library version 5.6 and been through the installation steps provided.
I have added the bin folder to my path environment as well as the include environment and the lib variables.
I also installed the Qt 5 package extension for visual studio 2015.
The first error I have when I attempt to create a Qt application project is:
"Cannot instantiate QTProjectEngine object!"
My second error:
When loading a template project and try to run the program in debug mode, I get the error: "The following error occurred: There's no QT version assigned to this project for platform Win32. Please use the 'Change QT version' feature and choose a valid Qt version for this platform."
