Strange error message from QtCreator

[broadpeak]

My environment:
Windows7
Qt 4.8.3
QtCreator 2.5.2

My project is QWidget based (not QML)

Before I'm debugging my project, I always get this message:

---

Debugging Helper Missing

The debugger could not load the debugging helper library.

The debugging helper is used to nicely format the values of some Qt and Standard Library data types. It must be compiled for each used Qt version separately. In the Qt Creator Build and Run preferences page, select a Qt version, expand the Details section and click Build All.

Continue Anyway Open Qt Options Turn off Helper Usage Hide Details...

I've tried to do this, but in "Details" section I have only disabled buttons (for QML)...
What can I do with this message?

For debugger helper working under windows

Tools->Options->Debugger->Cdb (click under the link "Debugging Tools for Windows") and Install the debugger tools

• Tools->Options->Debugger->Cdb->autodetect
• Tools->Options->Debugger->Debugger helper-> Debug Debugger helper
  Will it help for you

Thnx, but I see under CDB tab nothing what is "Install the debugger tools" and I can't see the "click under the link "Debugging Tools for Windows" too...

I've done what I'd read here, but this not solved my problem...
