I performed a clean install of the Arduino 1.6.2 IDE on Windows 8.1 and I'm able to program an Arduino Mega 2560 without issue. I followed the Tutorial on their site and successfully installed the board files, the correct driver is installed in Device Manager, and the IDE sees the open Comm Port. This report would have more information with Arduino: 1.6.2 (Windows 8.1), Board: 'SparkFun Pro Micro 5V/16MHz'Ĭannot run program 'C:\Program Files (x86)\Arduino/hardware/tools/avr/bin/avr-g++': CreateProcess error=2, The system cannot find the file specified I'm trying to program a Sparkfun Pro Micro 5v and I'm receiving the following compile error when I try to Verify or Upload.
