Tried that and no luck. Even running in compatibility mode it tells me that the update is not applicable to my system. But there's something else I hadn't noticed before and that's that my WM6.5 phone (HTC HD2) indicates in Devices and Printers that there's a problem. When I troubleshoot it it says that the driver for Bluetooth Peripheral Device is not installed.
However, everything seems to be working ok with the phone, but when I look at the properties of the device the manufacturer, model, serial number, etc. are "unavailable". Maybe I need a driver from HTC, except they don't have one listed!
