Hardcoded QMAKESPEC in Qt Creator?

Question

I installed the Qt SDK (Qt framework + Qt Creator), but I didn’t like the layout of the folders, so I deleted it (without deleting), moved the framework in one place and Qt Creator to another, and installed the Qt framework and Qt Creator separately placing them on top of the corresponding old.

The problem is that Qt Creator in the / Build Settings / Build Steps projects shows the old path to the specification file:
-special c: /qt/2009.03/qt/mkspecs/win32-g++

Setting the QMAKESPEC environment variable either on the system or in the Project / Build Environment does not change anything.

How to make Qt Creator see and use the new specification file location?
