Ruby Watir could not find firefox binary

Using ruby 1.9.3 and the latest version of watir-webdriver i get the following error when running a test script:

C:/.../selenium/webdriver/firefox/binary.rb:120in 'path': Could not find Firefox binary (os-windows). Make sure Firefox is installed or set the path manually with Selenium::Webdriver::Firefox::Binary.path=

I only just started getting this error after installing an older version of firefox in addition to a current version. I am using watir-webdriver NOT selenium webdriver. Here are my requires

require 'highline/import'
require 'watir-webdriver'
require 'win32console'
require 'term/ansicolor'
require 'base64'

Error is with this line:

browser = Watir::Browser.new :ff

I have uninstalled all versions of firefox and Ruby, and reinstalled only the latest. The firefox installation directory is in my PATH. Thanks in advance for any ideas.

Note that if you are using watir-webdriver you ARE using selenium-webdriver. Watir-webdriver is basically just a wrapper around selenium-webdriver. - Justin Ko

Added this line after my 'requires' section and it works

Selenium::WebDriver::Firefox::Binary.path='C:\Program Files (x86)\Mozilla Firefox\firefox.exe'

try this also, take the path where mozilla exe is installed.

<WebDriver::Firefox::Binary.path='C:\Program Files\Mozilla Firefox\firefox.exe'
=> "C:\\Program Files\\Mozilla Firefox\\firefox.exe"
