Error on Firefox Driver using Selenium/Python

Question

I'm getting an error when trying to execute a simple python script using Selenium. Here are the script and the error along with my environment information (I'm using a virtual environment). (I get a different error when I try to use the Chrome driver). Any help would be greatly appreciated.

// SCRIPT //

import mechanize
import urllib2 #requests web pages
from selenium import webdriver
from selenium.common.exceptions import NoSuchAttributeException
from selenium.webdriver.common.keys import Keys #allows us to press keys

import os
import re #regular expressions module

br = mechanize.Browser()
br.set_handle_robots(False)
br.set_handle_refresh(False)
br.addheaders = [('User-agent','Firefox')]

browser = webdriver.Firefox()
browser.get("http://applebees.com")

//ERROR//

Traceback (most recent call last):

This error happens when Selenium didn't find Firefox installation directory / firefox executable in its default location. Uninstall and Reinstall firefox with its default settings and run the script again.
