Ruby ODBC error

I am getting the following error when trying to connect to sql server
via odbc from a customer's computer

OLE error code:800A0E7A in ADODB.Connection
      Provider cannot be found. It may not be properly installed.
    HRESULT error code:0x80020009
      Exception occurred.

Here's a piece of the script

require 'odbc'
require 'win32ole'

   db = WIN32OLE.new("ADODB.Connection")
  db.open("Provider=SQLNCLI;Data Source=#{@server_name};Database=#
{@database};UID=#{@username};Pwd=#{@password};")

The script works from my computer. I have installed MDAC on the
customer's computer,

Any help would be greatly appreciated.
