Running the latest beta on Windows 10.
My preference is for Toad to always use the 19.8 Instant Client. In my user profile, ORACLE_HOME is set to this directory and the directory is also included in the PATH. The "make this the default home" checkbox has been enabled for all configured connections. Randomly Toad seems to prefer another client installation which I am using primarily for OLE DB support.
How can I prevent Toad from preferring this client over the instant client?
At the moment, I have 5 connections open that are using the instant client, but for some reason the connection dialog is defaulting to the other Oracle Home and won't allow me to change it.
