OCRA tries to load win32-api using "require 'win32/api'". It looks
like Ruby is trying to load the api.so library, but gets a permission
error. This could be because the library is already open. How do you
load it from your script? (Can you post a simple example script that
reproduces the error?)

What error do you get when using --no-autodll?

Here is my sample script which works with ocra-1.1.2:

  require 'win32/api'
  exit if defined?(Ocra)
  Win32::API.new('MessageBox', 'LPPI', 'I', 'user32').call(0, "Hello,
World!", "Greeting", 0)
