Why does some installers work and some not even if they are having a similar code?

Hey there,
I’ve tested various installers. Some work and some don’t even if they are having a similar code. Here’s a short list of which I tried. (-: doesn’t work), (+: works)

  • Amnesia Dark Descent: Humble Bundle -
  • Don’t Starve: Humble Bundle -
  • Robin Hood: The Legend of Sherwood: Desura +
  • LIMBO: Humble Bundle -
  • Monaco: What’s Yours Is Mine: Humble Bundle +
  • Lone Survivor: The Director’s Cut: Humble Bundle -

where it stucks:
when it normally comes to the election of the installation file (N/A:Please select the installer for this game)
it just says instead “file1 does not exist” or however the file is named in the code.
Here Amnesia as an example:

Does anybody now the difference/what to do?
