This is more for my peace of mind than anything else.  I can’t seem to find a site that has everything in one place. I always need it when I bork a Ruby installation and need to reinstall.  Place the ADO.rb file below into the following directory: c:\ruby\lib\ruby\site_ruby\1.8\DBD\ADO  You will need to create the directory first.

The file is here: ADO.zip
