Please can you test with StyleCop with the target and dll referenced in the project using local paths (eg ..\..\Build\StyleCop...).
(Also, please enable the right click on the messages window so it is more obvious I can copy and paste).

PS the Bug submitter had an error, can you provide more exception details as the target audience is developers.
