Unable to get programs to upload

Development Tools IDE 1.x
1

Hello,

I guess this is a common problem but as yet I've not been able to locate it among the many posts on this forum.

Firstly, my brand new out of the box Arduino UNO A000066 ATMEGA328 when plugged in has the green steady on light plus a flashing light above TX RX. I understand that this is normal as the UNO may well have the blink program already installed. ?????? Just to check the latter I have opened the blinking sketch in the Arduino environment, run the compiler and all is ok but when I upload I get the error message:

Arduino: 1.8.4 (Windows 10), Board: "Arduino/Genuino Uno"

Sketch uses 928 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Thus far I have used "tools" to check: the port and it is COM3 and the board which is the Arduino/Genuino Uno.

Just below the error dialogue box there is a blue ribbon and I note in the bottom right hand corner it says "Arduino/Genuino Uno on COM1"

I am desperately trying to get a program running for our local scout group but the above problem has me baffled and is preventing me from moving on. Any help and advice would be greatly appreciated.

ps I am completely new to this technology as you may well have guessed

set the Port in the Tools menu in IDE

Many thanks for your responses.

I have only one port listed in the tools menu: COM3, ie there are no other ports showing, both with and without the UNO connected.

Yes, I've clicked it but to no avail. There is obviously a mismatch. As I mentioned, in my original posting, just below the error dialogue box in the Arduino environment, there is a blue ribbon and in the bottom right hand corner it says "Arduino/Genuino Uno on COM1" My computer is working in COM3 and the Arduino in COM1. No, unfortunately I am not able to/don't know hwo to change the port to read COM1.

In my lengthy searches for a solution I did come across a, possible, solution on this posting, which includes a reply from me:

https://forum.arduino.cc/index.php?action=post;topic=334741.0;last_msg=3414218

It may be a solution but I don't feel particularly confident in messing/changing the content.

Go back a step. When you selected COM3 in Tools/Port and then tried to upload what error messages did you get? Are you saying you still get "Can't open COM1" errors even after you select COM3?

Hello Steve,
That's correct. I still get the same error message.
