Download Successful. Installation failed (Bundle ID’s don’t match).”

Hi,
I receive the error message "Download Successful. Installation failed (Bundle ID's don't match)." when using an application called AppFresh. This app scans my existing apps for available updates and if one is available, updates the app.
The error messages comes up each time I try to update one of my existing apps. Does anyone know what this error message means and how to solve it so I can use the app?
It’s a handy app once it works.
