An update.
After 3 hours of wasted time and spinning wheels, I gave up on getting ODBC to work on my Windows 8.1 PC If I get suggestions on this thread, I'll continue trying to get that to work.

In the meantime, I tried installing it on my hosted Windows 2008 server and was able to connect to data tables in Excel and Crystal Reports. .

What I'm trying to do here is to convert a handful of old Crystal Reports. When I run the report converter, I now get this error message:

Converting report <ARM New Cost Report BRK4a with GC.rpt>
7/19/2016 4:20:25 PM: (Error) Report <ARM New Cost Report BRK4a with GC.rpt> failed to convert: <Error: Missing method 'instance class CrystalDecisions.ReportAppServer.Controllers.SubreportController [ReportConvertor] CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument::get_SubreportController()' from class 'CrystalDecisions.ReportAppServer.ReportClientDocumentWrapper'.>
7/19/2016 4:20:25 PM: (Error)

UGH.

Ideas?
