I'm trying to connect my DFROBOT Bluno V1.6 to my Windows 7 laptop (32-bit version) and when ever I try to install the drive manually, my laptop keeps giving me an access denied prompt. Can anyone help out?

Thank you.

Hello wildwildwes,
What is your arduino IDE version? It should install the driver automatically.
Could you delete the driver,first and try again.
Please try to install the windows installer IDE, not zip file.

Are you using an USB 3.0 interface? Please try to connect a USB2.0 interface, and try again.
