Are you developing for Symbian? If not, the error under the setting shouldn't affect you. To get Qt creator working under Windows I Installed Qt Qt libraries 4.6.2 for Windows (VS 2008, 194 MB) and then added the bin folder under the Qt installation to my system PATH (in my case: C:\Qt\4.6.2\bin). I then installed Qt Creator. Qt Creator should then autodetect the Qt framework.
