hi,
I wish to ask you what is the right setting to run a report from a WPF (.NET Framework 4.5).
Reports are stored on a Windows 7 64-bit server; they were built using Crystal Reports 2008 12.0.0.683 and retrieve data from an Oracle 11g 11.2.0.1.0-64 bit DB. Runtime environment is CR Runtime Environment for .NET Framework (64-bit) v. 13.0.9.1312
The Designer is connected to Oracle via a ODAC 11.2.0.2.1 (32 bit) driver. WPF application uses a Web Service to call reports stored into remote server.
when a report is called, a "Unknown Database Connector Error" is got (caused by ReportDocument.ExportToStream).
In the server, both ODAC 32 and 64bit drivers are installed; driver locations are in PATH environment variable, and tnsnames.ora with link to DB are stored in network/admin directories. the reports repository folder has full control given to Everybody.
I dont know what this issue depends on. it seems Runtime Environment can not connect to DB, or maybe I am using an inappropriate driver. can you help me to fix this issue? thanks in advance
