Could not open library "iaccessibleDll.dll"

[ghost]

I've made a simple test, but my script fails with "Could not find 'ffi'" error. Thank you for any help!

require 'rubygems'
require "rautomation"

window = RAutomation::Window.new(:title => /Preventivo/i)
window.exists? # => true

Gets the failure:

I'm not sure why you're having this problem, but it might be caused by the fact that you're using 64bit Ruby. Can you try the same thing with using 32bit Ruby instead?

[ghost]

That's right. 32bit runs all right.

I am using rautomation to automate our windows application. However whenever I am trying to click on some button, it's throwing error message as specified below:

Solved the issue by replacing Microsoft Visual C++ 2012 Redistributable Package (x86) with Microsoft Visual C++ 2010 Redistributable Package (x86)

Thanks
