USB Bluetooth Adapter (169745): Installation Error: The required section was not found in the inf

Problem:
The installation on a Windows XP System fails giving the error message: "The required section was not found in the inf".

Solution: Disable the network connection
Disable all network connections your system has, especially a connection to the Internet.
Then reinstall the Bluetooth Adapter.
Explanation:
Windows XP tries to find the driver on the Internet when the network connection is activated. This then leads to the misleading error message about the INF file. Disabling the network connection during the installation resolves the problem.
