Also tried on another window (steam app, title: "Friends").
Also tried in both 16bit and 32bit screen color.
Also tried as admin user.

[Nakilon]

If I downgrade ffi to 1.9.18 the code:

require "rautomation"
RAutomation::Window.new({context: :window, title: "Friends"}).active?

emits:

Downgrading to rautomation 0.15.0 and ffi -v 1.9.0 --remote --platform=ruby causes Could not open library 'user32.dll' too.

With Ruby 2.0, uninstalled iteratively win32screnshot, rautomation, ffi and lowered versions of win32screenshot, until 1.0.6, where I got rake's executable "rake" conflicts with C:/Ruby22/bin/rake -- all the same CFUNC :enum_windows segmentation fault message.

I have the same problem, and this is what i did:

window = RAutomation::Window.new(:title => /Title/i, :adapter => :autoit)
Win32::Screenshot::Take.of(:window, rautomation: window).write!("test.bmp")

You can also try with: :adapter => :win_32 or :adapter => :ms_uia but i am not a really expert so i think that is not the best way to solve it.

I'm late but that's all :)

These problems might have been solved in version 3.0.0 (make sure that you are using 32bit Ruby, since win32screenshot does not work with 64bit version!).

I'm new to this, does this mean it's impossible to interact with gdi32.dll with 64 bit Ruby? Does FFI not provide a way? Having to use 32 bit Ruby because of this kinda sucks.

@tsujp unfortunately that's the case, yes. It is because RAutomation does not work with 64bit Ruby as of this moment. It is an older library, which is not actively maintained anymore, but PR-s are all welcome.
