The probe are not able to see all the DSN's already set via windows ODBC
Windows ODBC View:
UIM 8.5.x sql_response any version
Basically DSN must match the bits version of the OS. So if you tries to use a DSN created with ODBC Data Sources 32-bits on a probe installed on a 64-bit OS will not able to see the 32-bits and vice versa. DSN needs to be the same bits version as the Operating System of the robot where the sql_response is running.
Creates ALL DSN's with the same Operating System Bits version
