I don't know if this will help you or not, I was having a similar problem and found your post while looking for a solution. I found a solution just testing a theory, it ended up being that the compiler can't handle being in directories that contain a space anywhere in the parent path. Try putting the edison arduino ide folder directly on a root drive (C:\ for example) and make sure it is named without a space in it. Example C:\Edison_Arduino_IDE\
Excellent! Yes, now I can compile and, I think load the program. But the Edison is not blinking. I have two COM ports that appear when I plug both mini USB cables into the Edison mini breakout board. I tried them both. Only one give a transfer complete message, but shouldn't the Edison be blinking?
Excellent! Thank You so much, StevenH and onehorse. I was about to pull out the little hair that I've got. I had the Arduino IDE installed in "F:\Intel Edison". Changed it to "F:\Edison" and it works.
