title: Not a valid Win32 application... Python, PyInstaller, Windows7
body: <p>How can I know if I build a 32bit application or 64bit application?</p>
  
  <p>I have created .exe with Pyinstaller and it works fine on my computer (Win7 Ultimate 64), when I try to run the same exe on Virtual Machine (Win7 Home Premium 64) I get: Error 193 not a valid Win32 application.</p>
  
  <p>Python 2.7 32bit
  PyInstaller 2.1 (I think also 32)</p>
  
  <p>So isn't this 32bit application that should work fine on 64 too?</p>
