error message: avrdude: stk500_recv(): programmer is not responding
On a Nano
Widows 10
When out put to serial port, works so have right port and connections, plus was working on the port before version change
Problem started after going from 1.8.5 to 1.8.9

Worked on Nano until upgrade (why did I do that????), fails on other Nanos, so not processor
