ReportBuilder is currently compatible with the 32-bit version of Excel 2010 on both 32-bit Windows and 64-bit Windows. We are reviewing how to make ReportBuilder compatible with the 64-bit version of Excel (which of course will only run on the 64-bit version of Windows.)
JBarnes, Thanks for your suggestion. I'd like to ask a follow-up question. How will/do you use URL in data warehouse reports? How is it useful to you? Thanks very much, -Matt
