"Invalid data source definition: Unknown error" on heterogenous query Oracle - Sybase

With the 2 latest updates of Toad Data Point I am getting error message "Invalid data source definition: Unknown error" when I try to run a Heterogenous query between Oracle and Sybase database. This Works in 4.3 but not 5. I think this happened in the last 5.06 version but I would like to verify this. How can I download a previous version (only version 5.07 is available)?

Tip on how to debug this? Anyone else experiencing this?

Hi Arne,
I think it's currently not possible, I'll try to get you a link to 5.0.4.

Hi @arne-christian.harse Could you open a support ticket on and they will send you the older patch installer? Thank you

I found it in my Download folder. I have created a support ticket for the issue with the unknown error.

Hi @arne-christian.harse, We are sorry for the inconvenience. we found the root cause is the ODBC driver used by Sybase is get something wrong, and we have already update the ODBC driver. it would be released in the release 5.1.0.
