That's a link to a file on your computer. You're the only one who can see that file.

Have you selected the correct serial port in the IDE?
2)
Have you tried the 'old boot loader' option under tools->processor.
3)
Which operating system and IDE version?

(Assuming you're saying you made your own "nano-alike" or something) Did you burn the bootloader to the chip you used? Starting from a new chip, you need to do this. If your project uses a nano that you bought, you do not need to do this.
