There to things that cause that error one the reset didn't happen and two you didn't set the com port.

If it's a uno I would make sure I had the com port set right.


First: make sure you can upload GOBP  (The Good Old Blink Program)  On top menu go:


Upload. If same error, CHECK
- Tools>Board  (Right board?/)
- Tools> Serial Port (Right port??)  IF Serial Port grayed out, your board / USB / ?? is not working.

Let us know what's happening...

Thanks for the suggestions.  Karma3 nailed it.  I didn't have the com port set correctly.
