Hi! I have an Arduino Duemilanove and I want to use it in Windows 7. I already install the latest FTDI drivers, and the arduino appears as a USB serial port in the device manager. When I try to upload code to the arduino always says the following:
avrdude: ser_open(): can't open device "\.\COM3": Access is denied.
I already try to change the COM port number and the same happens again and again.
