Qtcreator 2.7.0-RC Qml2Puppet:

Hi I am using Qtcreator 2.7.0-RC on Windows, and I downloaded the qml2puppet.exe binary (msvc 2010) When I tart the designer, the qml2puppet processes failed after 1 seconds, Is there somewhere a log file about this binary? Sould I compile qml2puppet every time?? Thanck you
