A3. No, there will be no issues for customers continuing to run the Relais 2014 client once we have upgraded the Hosted Service to Relais 2016.
Q4. When running the “CreateODBCexe” utility on a staff workstation and a user with Administrator rights enters their credentials and CreateODBC.exe utility completes successfully, but when you try to use Relais you still receive indications that the Relais applications cannot find the required ODBC entry.
A4. In this situation Windows has determined that the user running this utility does not have sufficient privileges to allow the CreateODBC.exe utility to complete successfully. This issue only occurs when running the CreateODBC.exe utility on windows Vista and higher.
The user data sources are stored on the HKEY_CURRENT_USER tree in the windows registry
If someone with Administrator rights has entered their credentials into this prompt, the CreateODBC.exe utility completes successfully but the ODBC setting is created under that user's profile and not the user that is currently logged into the staff workstation.
The Relais ODBC entry must appear under the “User DSN” tab in the windows “ ODBC data Source Administrator”
Temporarily add the user's account into the windows local administrators group. This ensures the user in question has sufficient privileges to allow the CreateODBC.exe utility to add the required entries into the HKEY_CURRENT_USER tree under their profile in the windows registry.
Once this is done you can remove the user account from the windows local administrators group.
