Well I read that post and found no help from it. I did that already before sending my post here. If you mean that I should ask Google first... well I did that for a good 2-3 hours and tried several thinks which supposed to solve this issue but none of them worked. So eventually I tried to ask some help from here. Maybe I am not that good with the Google...
Anyway I am still trying to find a solution simultaneously from Google and best I found is this thread:
https://forum.arduino.cc/index.php?topic=455104.0
However do not have Win10 and I have no idea what "adding document location to library" means and cannot find the answer from Google either...
By security software do you mean antivirus? That would be McAfee.
