I’m using a Windows 7 operating system. I’ve just downloaded the driver successfully. Once I got the Pronterface program up and running, it showed a COM7 available, but will just say “Connecting…” forever. I close the program and open the pronterface.exe text file and it says:
serial.serialutil.SerialException: could not open port COM7: [Error 5] Access is denied.
Did I just forget a step in this set up process?
