I have tried do submit an application via Xcode (as well as the application loader) to the Apple store, and I received the following error:
Invalid Bu
For me the answer was to
go to
/Users/myusername/Library/Developer/Xcode/Archives
go to the current folder for the latest archive.
right-click the .xarchive and select 'show package contents'
navigate inside the 'products/applications' directory
right-click the myAppName.app and select 'show package contents'
delete the exe at the very bottom that was not named myAppName.exe
