Consider the following scenario. You connect a Microsoft Bluetooth mouse or a Microsoft Bluetooth keyboard. The mouse or the keyboard uses the "First connect" technology. Then, you install the IntelliPoint or IntelliType Pro setup software.
During the installation process, the Connect your mouse and keyboard dialog box appears. You follow the steps in the dialog box to start the connection with the mouse or with the keyboard, and then you click Next. The setup software tries to put the Bluetooth transceiver into a software-managed Bluetooth mode, and then it tries to connect to the mouse or to the keyboard through a Bluetooth connection.
In this scenario, the connection fails, and the Connect your mouse and keyboard dialog box appears again. If you try to connect either the mouse or the keyboard again, the connection fails again.
