can not install driver


i just purchased a blue-tooth adapter 4.0 USB and i can not install the driver in windows 7 64 bit the PC see the adapter but won’t let me install driver BCM20702A


Hi dylan,

Thanks for posting your question here about installing the drivers for our Bluetooth adapter on Windows 7, I’ll be happy to help.

To troubleshoot I’ll need a bit more detail about the error you see when installing the drivers. Also, can you say what error code (if any) is listed for the device in device manager?

Also, what is the make and model of your comptuer? Does it have any other Bluetooth adapters either built-in or external?

Let me know these additional details and we’ll figure out the next steps.

HI Dylan,

Thanks for letting me know these details, here’s a couple more questions.

  1. Is the blue light on the adapter illuminated?

  2. Have you tried to run the install with the bluetooth adapter plugged into another port?

  3. Does the installer finish or does it fail before completing?

  4. Is the Bluetooth support service running? To find out hit the Win + R hot key and then type services.msc – look for the Bluetooth support services entry and make sure it’s started. If it’s not running try starting it and running the installer again.

Also, make sure that you have the adapter connected when running the installer.

Let me know what you find and we’ll figure out the next steps.

Hi Jerome

  1. The blue light is on
  2. When plugging in the adapter the PC recognizes it and on the devises. it shows with the yellow triangle exclamation mark
  3. the installer finish and does not fail
    when using the trouble shoot it comes up with you need to install when attempting it unable to install driver tooth support is running
  4. tired to re install still no success it state install was a sucess

adapter was connected

Adapter did not cost much so coming to the conclusion to give up.
