I installed Qt SDK (Qt framework + Qt Creator) but didn't like the layout of folders so I deleted it (without uninstalling), moved framework in one place and Qt Creator in another and installed Qt framework and Qt Creator separately placing each over the respective old one.
The problem is Qt Creator in Projects/Build Settings/Build Steps keeps showing the old path to the specification file:
-spec c:/qt/2009.03/qt/mkspecs/win32-g++
Setting QMAKESPEC environment variable either in the system or in Projects/Build Environment doesn't change anything.
How can I force Qt Creator to see and use new location of the specification file?
