I installed qt-opensource-windows-x86-msvc2012_opengl-5.3.0 then installed qt-vs-addin-1.2.3-opensource. I had VS 2012 installed on my Windows 7 machine.
So, for making first example I tried to create a new project on the VS 2012 IDE as follows:

New Project -> Qt Application -> named Qtest as of name for project -> OK -> On the overview tab clicked next. then I got below message:

I clicked Yes then Next and then Finish. this time I got this message:

When I clicked OK, it returned me to first previous window of naming the new project.

How to solve this problem and how to use VS 2012 for Qt please?
