Have been using the IDE for other boards fine. This time I tried to use it with Raspberry Pi PICO. I followed the installation and no errors.
When I plug in my board it doesnt show up as a COM port in device manager. It does show up in Other devices claiming the driver is not installed. 1st time plug in Windows indicated it installed successfully.

Meant to add this is on a Windows 10 PC
Did you do the bit where it said after the first load of your program:-
After the first upload, this should not be necessary as the arduino-pico core has auto-reset support.

This selection allows the auto-reset tool to identify the proper device to reset. Them hit the upload button and your sketch should upload and run.
I used these instructions
I dont see the topic above mentioned.
FWIW when I plug in the Pico it now shows up as a

This was after installing then uninstalling Arduino Mbed OS2

I have used the earlephilhower implementation settings and the information needed to get it going is here
Basic upload instructions
I have not had trouble after following these instructions. Note when first plugging a Pico into an Arduino you have to be holding down the reset button during when you insert it into the USB. This might need a friend. Those without friends might need a switch arrangement in the USB lead.
