com.sun.jna.platform.win32.Win32Exception: The system cannot find the file specified.
This indicates that for some reason the Arduino IDE is unable to access your Documents folder. Maybe that folder is on a drive that is not currently accessible. Maybe it's a permissions problem.
It's best to find the true solution for the problem but if you can't do that, here's the workaround:
-
Install the hourly build of the Arduino IDE from:
http://www.arduino.cc/en/Main/Software#hourly -
Run it in portable mode by following these instructions:
