What I want to check out is the hardware angle. I've found many folk do and say what you wrote but then discover there is no Bluetooth radio in the machine.
I went to Toshiba web site and downloaded Bluetooth stack and installed it. I now have a Bluetooth icon showing on my computer, but the computer still cannot find any bluetooth items, I have mobile phone and the speaker; it still says No Connection. Windows support says go to Control Panel, select Hardware and Sound then Add a Device. There is no Hardware title and under the Sound Title menu there is no option to 'Add a Device'. So much for Windows support!!
In control panel Bluetooth Local COM it says the Bluetooth device is not ready. Both speaker and mobile phone bluetooth are on. I have run out of ideas now. Although whilst I was on the Toshiba site, as it was so incredibly complicated and time consuming to get to the downloads, I downloaded everything I could see that might relate to the Bluetooth, just in case there is more needed!
