I have a server installed Windows Server 2003 x64, and it also has a license for x64 Qlikview. at the beginning I had problem with the Oracle and ODBC connection (I do not see in the display manager of the ODBC driver) but it solved the problem by using Odbcconf.exe another folder.
Now with Qlikview it does not recognize my name from the database and therefore it does not display tables (I think it always points to the former Odbcconf.exe)
is that you have an idea? thank you.
