How set local Windows Debugging Symbol on Qt Creator?

[Arrandale]

I downloaded Window Debugging Symbol from Microsoft and installed on C:\symbol

Options->Debugger->CDB Paths

What to do now?
Just add C:\symbol to "Symbol Paths"?
What is "Source Paths"?

;) A lot of work to set Qt Creator to use with MSVC.
Should I use Qt Add-in instead?

I tried to install Qt-Addin.
It's worst. lol
Just create project an error message pop-up!
It's happend to me long time ago I though It was fixed but still...
