Application.app/Contents/MacOS file issue

[sgmurphy19]

If I take the file App from the package content folder App.app/Contents/MacOS and download it using Qhttp I am unable launch the app using the downloaded file.

If I grab the same file with an ftp program or straight from the server and copy and paste it, the app launches (so I know it is a good file).

Anyone know why this is the case?

Also, if I email that file to myself and try to use it, it doesn't work either... not sure if these are related.
