Office 2003 Svc Pack 1 not yet supported
Be wary of upgrading a Office 2003 install to Service Pack 1 (released 7/27/04). The service pack updates VBA to version 9972 which Test Partner doesn't yet support.
Re: Office 2003 Svc Pack 1 not yet supported
Service Pack 2 for Test Partner 5.2.1 is available now. This will allow support for the newer VBA version.
