Can't upload a program

Development Tools IDE 1.x
1

I got new Arduino Uno r3 board.

Installed latest Arduino IDE 1.6.7

Uploaded latest firmware using ATMEL flip software.

updated Arduino drivers

It assigned com18 in ports

Then opened Arduino IDE
Choosed "Arduino/Genuino Uno" under boards
Choosed "COM18(Arduino/Genuino Uno)" under port

I tried to upload blink LED program example.

It showed an error as such

avrdude: ser_open(): can't open device "\.\COM18": Access is denied.

Please help me.. It's my first time with Arduino and it seems impossible to deal with this

Hi I too am a raw beginner and I seem to have exactly the same problem.
I am using Windows 7 Home Premium.

Arduino Uno R3 SMD edition

IDE 1.6.7.

The assigned port is COM7

My error message is

avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.

The LED 13 on the board flashes when the board is powered up and not connected to the computer. The reset button has no effect on this.

I am following your advise to change the COM port - fingers crossed

I am cheered up to find that I am not alone.

Cracked it - at least on my machine.

I have loaded an older version.

This time COM8 was assigned to the board and the first run of Blink failed but I received an error option.
I was told that COM1 was being tried and was failing and I was given the option of changing to COM8 which I did and the system is now running fine.

Thanks for your inspiration.
