Amnesia patch for Justine issues?

Your main game seems to be outdated then.
Really silly but when you have an older version of the game it fails to overwrite the launcher.
Had it myself although with me it showed up but it just wouldn't start saying it couldn't find (forget the name of the file) after checking the file was actually there.
Granting permissions and turning of read only then reinstalling fixed it for me.
