avrdude: ser_open(): can’t open device “\\.\COM3”: Access is denied

I get this error message when i try to upload code to my arduino. Does anyone know what is going on?

I have installed the proper drivers and it works fine. My port appears on the menu and it is the corresponent to the device.

bless
