This issue may occur because the Bluetooth drivers provided by Microsoft support a different set of profiles than the drivers provided by third-party vendors.

Microsoft-provided drivers are also signed, and will therefore be installed instead of a third-party driver for supported Bluetooth adapters. The Windows XP SP2 Setup program will try to detect if a third-party driver is present. If the third-party driver is installed, the Microsoft- provided Bluetooth drivers will not install.

This action makes sure that an existing configuration is not modified. If both provided drivers were installed, and the Bluetooth Radio is connected to
the computer, the Microsoft- provided driver would load because it is the one that's signed.

If the missing functionality is critical, you may restore the third¬party support. Follow the steps below to do this:
NOTE: The following steps assume that the third-party software is installed. If it is not, install the software according to the manufacturer's instructions. Then follow these steps from the point in the installation process where the adapter is connected to the computer. o Right-click on "My Computer", go to "Properties", click on the "Hardware" tab and then on "Device Manager".

o Locate and then expand "Bluetooth Radios" by clicking on the "+" sign.
o Right-click on the Bluetooth adapter, and click "Properties".
o On the "Driver" tab, click "Update Driver" button.
o Install the updated driver manually by using the "Have disk" option in the Wizard. Locate the manufacturer's installation files, and find the .inf file that is required to install the driver. o Complete the manufacturer's software installation steps. Manufacturer's instructions will be in a readme text file, or a Word or PDF document on the disk.

Now the third-party drivers should work. If at any point you re-enumerate the Bluetooth adapter, the Microsoft driver will be reinstalled, and you must repeat the procedure. This issue will occur only if the third-party driver is
