title: How to run exe file from python?
body: <p>I try to run a exe (In the background) from a specific path in my local python project, with the os.system libary.
  I have managed to change folders like 'cd' Command, but i can't run the file.</p>
  
  <p>This is for a python project running on Windows 64BIT, Python 3.5.3</p>
  
  <p>the file.exe is at the "programs" dir.</p>
  
  <pre><code>import os
  os.system("cd C:\Users\User\AppData\Windows\Start Menu\Programs")
  subprocess.Popen("file.exe")
  </code></pre>
  
  <p>Error:</p>
  
  <blockquote>
    <p>{OSError}[WinError 193] %1 is not a valid Win32 application</p>
  </blockquote>
  
  <p>I saw other posts about this issue but i couldn't resolve it.
  Any ideas?</p>
