Oracle drivers

The error message when I am trying to run VB 6 application on windows 7 the error message get generated:

Run-time error '-2147467259 (80004005)';

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

I am running Oracle 9 data base.

How am I supposed to fix this error. If somebody would be able to guide me how to fix this problem I would appreciate it very much. Regards. Gregory

I believe VB6 is a 32Bit app?

If so, you need the 32Bit Oracle ODBC Client and create a 32Bit ODBC DSN.

If your windows 7 is 64Bit, there are two ODBC admin tools:

You can download the Oracle Client from here:

You will need two downloads:  Basic and ODBC.

You will also want the version since, I believe, that is the minimum one supported on Windows 7 and I'm not sure if the 11g clients will connect to an Oracle 9i database.
Once you get both the 32 and 64 bit Oracle drivers installed if you need to manage them as named system data sources make sure to use the appropriate windows administrative tool for each: http://msdn.microsoft.com/en-us/library/ms712362(v=vs.85).aspx

I wish Microsoft could consolidate these as it messes me up all the time too!
