Hi Greg, The error occurs as soon as I Open() the connection. I do have multiple homes, but the home selector is pointed to the correct one, the 817 version. But yes, the 817 version is installed in the ora92 dir, strange? I've tried the permissions test, and that still didn't work. And no, I can't even create an oledb connection when i try to add and test a Data Connection from Visual Studio. I appreciate your help.

Public Function GetConnection() As System.Data.IDbConnection
        Dim objConnect As System.Data.IDbConnection


        Select Case p_strDatabaseType
            Case "SQLServer"
                objConnect = New System.Data.SqlClient.SqlConnection(p_strDSN)


            Case "Oracle"
                objConnect = New System.Data.OleDb.OleDbConnection(p_strDSN)


            Case "Netezza"
                objConnect = New Microsoft.Data.Odbc.OdbcConnection(p_strDSN)


            Case Else
                Err.Raise(InvalidDatabaseType, Me, "An invalid database type of " & p_strDatabaseType & " was encountered.  Please check your database settings.")
        End Select


        objConnect.Open()
        Return objConnect


    End Function
