It means exactly what it says.

The account that the application is running under does not have the right permissions on the folder in question.

Make sure you have read/write/create permissions on the folder you are working with.

You will need to give your application authentication to the hemanth.vemu user. You can use LogonUser to do this. It can validate both local and remote users. For local users simply pass the machine name in place of the domain.
