Drivers on 64bit and 32bit .NET application.

822910

Using .NET 2010, C# or VB.NET.
Development Platform PC is using 32 bit OLE Driver, Oracle.Dataaccess on a 64 bit machine.

When the program are deployed to a new 32 bit machine, the program works fine. But, when deployed to a 64 bit machine, it does not work, simply cannot access the database and the OLE DB driver cannot be loaded error messages.

What am I doing wrong and how can we fix this ?

Thanks ahead of time

Microsoft does not provide 64-bit Oracle OleDB drivers, so you need to install the Oracle 64 bit OleDb driver, then change your Provider name from MSDAOra.1 to OraOLEDB.Oracle.1
