title: Can I use 32bit dll or exe in 64bit python?
body: <p>When I use CDLL to call 32bit dll in 32bit python, it works well. 
  But unfortunatelly in my 64bit win7 os only installs 64bit python, when calling it turns: it is not a effective win32 app!</p>
  
  <p>Can I use 32bit dll or exe in 64bit python? Or I have to install 32bit python instead?</p>
