I am using Toad for Oracle 22.214.171.124 on Windows 10.
I have two Oracle Instant Clients installed: 12c 64-bit (126.96.36.199) and 19c 64-bit (188.8.131.52).
When reviewing the Oracle Homes dialogue I see both Instant Clients.
Within Toad for Oracle, when I connect using the 19c version and Execute SQL via SQL*Plus, then the sqlplus.exe for 12c is launched (not 19c).
My Windows environment path has the 19c Oracle Home listed first.
How do I specify which sqlplus.exe to use when selecting the option Execute SQL via SQL*Plus?
Thanks in advance.
