No Port

Using the Web Editor. I can select my Uno, but can't select the "port". The "upload" arrow is greyed out.
No "Tools" menu to select "port" from. Tried downloading and installing Arduino Create Agent but got message saying that "...this program cannot run on this computer (Windows 10).
Completely lost and frustrated. My Uno doesn't seem to "run out of the need to install anything".

Try using the standard Arduino IDE, which you can download for free from here:

Hi @FreemansArduino,
have you followed the Getting Started wizard to install the plugin?
