Hello

I'm new to Arduino and I need your help.

I am at the beginning stage of trying to upload to the board. The error message I get below indicates that access is denied to the COM4 port. I have followed the trouble shooting steps but I am still not having any success.

Any help you could send me would be greatly appreciated.

Thank you in advance for any tips you can send me.

Access Denied generally indicates that another program has the serial port open. Exit that program or tell it to disconnect from the port.

Very rarely, we see reports of people who have some sort of "modem manager" software, or other software installed designed to connect to some serial device, which runs in the background, assumes any serial port is the type of device that it's designed to talk to, and automatically connects to it and starts trying to talk to it as if it is that type of device. This is quite unusual nowadays, as very few people have anything related to old school modems on their computer....

Thank you to every one who responded to me. I followed spycatcher2k's advice, this seems to have solved my problem.

"Select UNO from the boards menu (The hint is the work UNO on your board).

Close the IDE.
Restart your computer.
Start the IDE.
Open and upload 'Blink' from the examples menu."
