Stack Detection

Does anyone have any experience detecting which stack is installed on a
device programatically?

Specifically I'm targeting the Widcomm and Microsoft stacks, so I need
a reliable way to determine which is the running stack.

Any help would be greatly appreciated.

I solved this.

You can simply call the BluetoothFindFirstRadio API and if it returns
NULL attempt to use the Widcomm API's.
