Hi,
I have three nearly similar installationes with Arduino 1.8.5 and B4R 3.90, but one of the installationes makes horrible errors, unfortunately the one, i use to work with.
All libs are actual and the harddisc is tested. I read, that missing averdude reference is in Arduino AVR boards packet. Tried several new installationes. Any idea, what can be the reason? Can there be a cross dependence ob libraries, I should delete or a wrong error description?
many thanks
