I'm writing an App using python with a GUI in wxpython (for cross-platform compatibility) and packaging using py2app. It has to have the 'Open in 32-bit mode' checkbox checked (in the 'get info' dialogue) in order to run. Where is this flag actually stored? I can't find any preference file that registers it. I want to be able to distribute the app with this option already checked instead of having to instruct the user to do it. Anybody know? Many thanks in advance!
