avrdude done.  Thank you.

user31105: Can be many causes since you did not provide more info (like what circuit, what application). But in general:

Wrong software installation
Try another similar chip/device, maybe this one is broken
Is it recognized by USB at all?
Bad USB cable
Did you select the right board in the IDE (Arduino IDE?)

Possible solution:

Reinstall IDE
Change chip
Change Arduino
Use different cable
