Before installing the handheld software the BlackBerry Desktop Manager must be installed. The BlackBerry cradle or USB cable must be connected directly to the desktop/laptop and not through a docking station / port replicator or USB hub.
Warning: It is critical that the computer used during installation is not allowed to enter stand-by, hibernate, or suspend mode. Failure to prevent this results in a failed install and possible permanent damage to the device.
Launch BlackBerry Desktop Manager then connect the device to the computer using the cable/cradle. Navigate Start > Programs (All Programs) > Blackberry > Desktop Manager. With Windows 10, click Start > Apps icon (located in the top-left corner) > All apps (located in the bottom-left corner) > BlackBerry > BlackBerry Desktop Software / Desktop Manager.
Click Update Now. If the window does not appear, open the Application Loader.
If prompted, verify the PIN number of the device and enter the device password (if applicable) then click OK.
From Update Software, click Start.
