title: qt creator needs a compiler set up to build. configure a compiler in the kit options, after adding compiler, cannot produce code for the qt version
body: <p>alright.. i downloaded and installed qt 5.1.1 (msvc2012, 64 bit) on my windows 7. i tried to run a simple qt gui application...  and this is what happened:</p>
  
  <p>when i pressed "run"... there was error.. it said:</p>
  
  <p>"qt creator needs a compiler set up to build. configure a compiler in the kit options"</p>
  
  <p>then i found i had a list of 4 compilers to add from... when i added mingw... it said:</p>
  
  <p>"the compiler mingw cannot produce codes for the qt version 'qt 5.1.1 MSVC2012 64 bit'"</p>
  
  <p>it did the same for all the other compilers that i chose from the list of 4... nevertheless, i pressed "run" again.. as expected, it did not work... and this was the compile output:</p>
