title: Qt creator won't run app after compiling
body: <p>I checked out a Qt project hosted on google code with SVN to a local folder. When I opened it on Qt Creator, it managed to compile the project, but when it tried to run the compiled program, an error message came up on the application output:</p>
  
  <p><em>The process could not be started!</em></p>
  
  <p>What is wrong?</p>
