Did you play the game all the way to the end, where you get an onscreen notification "Making end-of-chapter autosave and exporting choices."? You may have stopped too soon (and may have also missed the little bonus scene that comes after the ending and the end-game summary).

Well, that is peculiar. It does live in a different folder from the save file, and only under the app_data sub folder (saves live both under the install folder and under a different appdata subfolder. Perhaps some issue with security settings or overactive anti virus software. At any rate, not to worry, that final save file can be used as an alternative to the choices export (I'm expecting there to be some people who just back up their install folder and move machines, losing access to the choices export, and it can use that as a fallback), so if you have that stored you should be fine too.
