Hi,  
I am new to IronRuby. I have installed IronRuby1.1. When I execute my  
IronRuby script I get an error:

unknown: no such file to load – gem\_prelude.rb (LoadError)

Can someone tell me why this error is occuring???  
I am trying to automate using Bewildr.  
This is my script:

require ‘rubygems’  
require ‘bewildr’  
puts “hello”  
@app = Bewildr::Application.start(‘C:/Documents and  
Settings/Desktop/ExpenseItStandalone.exe’)

Thanks in advance,  
Sophia
