Hi Hari,
If the user has the MCR already then you can just provide them the 'for_redistribution_files_only'. Let me explain what all these folder means.
1. for_redistribution - This will have 'MyAppInstaller_web.exe' which can be used to install both MCR and the application.
2. for_redistribution_files_only - This folder will contain the apllication as well as other files that are required to run the application. This can be distributed for the end users.
3. for_testing - This folder will also contain your application along with other log files. You can use this to test your application from your end.
