2)If your BlackBerry device is connected to a laptop in a docking station, disconnect the laptop from the docking station and connect the device directly to the laptop.
3)If a third-party program (e.g. virus scanner) is using the same COM port as BlackBerry Desktop Manager, close the third-party application to free the COM port.
4)If you are using a USB adapter to connect your BlackBerry device to a serial port on your computer, temporarily connect your device to a computer with a USB port.
5)In Desktop Manager, double-click Application Loader.
6)Use Application Loader to install the device software.
