QtCreator 5.7, Windows 7, Intel (HD) Graphics Family, OpenGL V 3.1

[Mean Mike]

In trying to run a Qt app on a Windows 7 laptop it says the following (and keeps repeating the):

shader compilation failed: 
"Failed to create D3D shaders.\n"
QOpenGLShader::link: Failed to create D3D shaders.
Failed to create D3D shaders.

QOpenGLShaderProgram::uniformLocation( matrix ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( color ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( textureScale ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( dpr ): shader program is not linked
QOpenGLShader::link: Failed to create D3D shaders.

The output above is from the 'Application Output' window in QtCreator.

I am using windows 7, Intel (HD) Graphics Family: Driver version 8.15.10.2559, OpenGL version 3.1

The OpenGL version is from OpenGL Extensions Viewer The Driver version was retrieved from Screen Resolution->Advanced Settings->Properties->Driver

More details:
The app runs on Linux (Ubuntu 14.04). I moved it without any modifications to my Windows 7 laptop. I'm using Qt 5.7 on both laptops (Linux & Windows). It built on Windows 7 without any complaints. It built and ran on Linux without any complaints. I thought I might have an OpenGL version issue, but OpenGL Viewer says that my system has OpenGL 3.1.
