title: py2exe/pyinstaller: execution failure
body: <p>I programmed a simple, little game with wxpython and created an .exe of it with py2exe (and in a 2nd try with pyinstaller). I also programmed an installer which just creates a folder and copies all the game files into this folder. I also created an .exe for this installer. Everything works fine on Windows 7. But on Windows XP i get this problem: My installer.exe succesfully works, but when I start the .exe from my game then I get this error:</p>
  
  <blockquote>
    <p>foo.exe is not a valid win32 application</p>
  </blockquote>
  
  <p>I use python 2.7</p>
