Windows 7 Qt 5.3.2
when I run a simple"hello world" program, I get the error

09:42:14: Running steps for project HELLO...
09:42:14: Could not start process "D:\qt5.3.2\5.3\mingw482_32\bin\qmake.exe" "D:\Qt\HELLO\HELLO.pro" -r -spec win32-g++ "CONFIG+=debug"
Error while building/deploying project HELLO (kit: Desktop Qt 5.3 MinGW 32bit)
When executing step "qmake"
09:42:14: Elapsed time: 00:00.

any giant could tell me how to fix it?
