N.B. I'm a tech support pro with decades in the biz so you don't have to be nice if I'm doing something obviously wrong (although it is appreciated)

This report would have more information with

Hi! I'm sure we can figure this out together quickly. What instructions are you following to install? Did you add through the board manager?
