Can not debug using Qt Creator on Windows

I am new to Qt. I have just installed Qt SDK version 1.2.

My platform is windows 7 64 bit
Visual Studio 2010 pro 32 bit installed ..
Now I have installed Qt SDK 1.2 (which has Qt creator)

I have created a test project and it runs fine but I can not debug it. When I debug the program I get this error message

• The preferred debugger engine for debugging binaries of type 'x86-windows-msvc2010-pe-32bit' is not available.
• The debugger engine 'Gdb engine' will be used as a fallback.
• Details: There is no CDB binary available for binaries in format 'x86-windows-msvc2010-pe-32bit'

It seeems to automatically have picked up my vs 2010 compiler as I can see in the project build settings but seems like it can not use the debugger for some reason..

According to this documentation, you need to download and install the Debugging tools for Windows.
