Just to make sure - I see you've used exactly the same path Intel_JEspinoza has provided - the path you're entering there should be the one where you've unpacked the Arduino IDE.
Have you actually unpacked it into C:\arduino-1.5.3?
If yes - please show what's inside of the C:\arduino-1.5.3\hardware\arduino\x86\tools dir.
If not - use the "Browse..." button on the screen number 4 on your last screenshot and point it to the actual directory the Arduino IDE is unpacked into.
