TPT DSN Error - response (7) by feinholz

Yes, it was related to 64-bit TPT.
The Microsoft driver needed something set explicitly whereas the DataDirect driver did not (accepted our default setting).
 
We always recommend that you keep current with the latest efixes/patches of our client software. By that, I mean if you have version 14.10, then keep up-to-date with the patches. If there is an issue, we cannot assist unless you are at the latest version.
 
If you have, say, a 14.10 version of the DBS, it does not necessarily mean you should upgrade your client to 15.0 or 15.10. Most people try to keep the client and database versions at the same level.
 
However, our client software supports 3-4 releases of Teradata, so you will not run into issues if you have an older database release than client.
