Ok I'm getting some errors here .. this is what I did ... I downloaded the minGW libraries, and then I started its install .. I was asked where to install the files, and I chose C:\Qt2\

I was also asked where is minGW installed .. I gave the C:\NokiaQtSDK\mingw\ directory ......... C:\NokiaQtSDK\ is where I had installed the Nokia Qt SDK BETA earlier on ..

I then went to Tools --> Options --> Qt4 in Qt Creator and clicked on the '+' button on the right, and indicated the C:\Qt2\qmake\qmake.exe path for the qmake file ..

Immediately, it said 'Qt version is not properly installed, please run make install' in the bottom section of this dialog box ...

I closed it all, and went to 'Projects' in the left pane, clicked on the '+' button, and selected Desktop.

The error reported here now is 'This Qt-Version is invalid', next to the 'Qt Version' list box (which has the newly added '4.6.2' entry)

Now when I try to build a project for the Desktop target, I get the following compiler error:

Qt version 4.6.2 is invalid. Set valid Qt Version in Tools/Options
Qt version is not properly installed, please run make install

Error while building project pixmap (target: Desktop)
