I just saw your post, but will assume you have a solution by now. If you do not it would be usefull to know what is the error you are getting. If the machine does not have CR installed on it you would need a viewer application. Business Objects has a free viewer that may meet your needs and can be downloaded from them. If it does not meet your needs there are number of other free report viewers available.
Hope this helps
