Ruby - watir : Failed to get IEnum Interface

Question

I'm using windows XP and I need to use watir with ruby, the installation went pretty well, my last try was following the instructions here Failed WATIR installation Server 2003 and everything was ok except for this "ERROR: While generating documentation for builder-2.1.2" then the installation finished with no more problems.

The problem is when I try to run a sample script to execute a google search I got an error when the set function is called, so far I haven't found any useful information about it, if anyone could give me a hand it would be great :)

btw, here http://www.mail-archive.com/[email protected]/msg07722.html they say that it is related to WIN32OLE but they don't explain how to fix it (or at least I didn't get it :s )

The versions I've installed are


    ruby -v
    ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

    gem env

The error

The sample code (Search.rb) I removed comments and other unnecessary lines


    require "watir"

    test_site = "http://www.google.com"

    browser = Watir::Browser.new
    browser.goto test_site
    browser.text_field(:name, "q").set("pickaxe")  # here is the error when set is called
    browser.button(:name, "btnG").click
    browser.close

Watir can't find IEnum interface thread that you link to says:

my best suggestion is to uninstall and reinstall Ruby, then re-install Watir on top of the new Ruby

and that would be my advice too.
