I'm running a test to display a report from a Delpni 2010 application. I connect to MS-SQL Server 2005 database using Native Client 2005 or 2008. In a PC with XP Pro 32 bits and CR X1 full product (developer ed.) and in other PC with W7 Pro 32 bits and CR XI R2 full product runs fine. When I run it on a W 7 Home Ed 64 bits with CrystalReports11_5_RDC_Reportengine and CrystalReports11_5_RDC_Runtime merge modules installed and Native Client 2008 64 bits, it fails with "Error 536 ... Unable to connect, Incorrect log on parameters. SQL.SetQuery <PEGetSQLQuery>".
The same application also display a simple report (no database connection) without errors, so the runtime is working. I also tested the server connectivity with ODBC using the native client without errors.
I think the culprit is a missing dll in the runtime module. Any ideas?
