1. Why is my configured application not starting ?
Make sure you use the correct path and use double back slashes (\\). Use the Test button to see if the Bluetooth device is really discovered (check te log messages).
2. I deinstall BlueStarter now I get an Messagebox: 'Can not start BlueStarterServer' ?
This is a known issue: re-install and switch off interval checking, the deinstall will now be done correctly.
