We have SAP Crystal Reports for Visual Studio (version 13.0.10) running under Visual Studio 2013 from a Windows 2012 (64-bit) server with the Oracle 12c ODP package installed.
We have some old Crystal Reports .rpt files that were created under Crystal Reports 10 that were created to directly connect to Oracle (Oracle 8 and 9 at the time) - and we would like to be able to utilize these files as is in the CR for VS environment. When I try to connect to the database or preview the reports, I get the error "Failed to load database information. Details: The database connector 'crdb_oracle.dll' could not be loaded. The correct version of the database client for this database type might not be installed." It looks like crdb_oracle.dll does exist on the server - so I'm wondering if the issue is that we need to install the complete Oracle client (not just the ODP) - or is there more to it? Also, will this work with Oracle 12?
Please let me know what I can do to make this "backward compatible" with Oracle so that we can reuse these .rpt files. Thanks in advance!
