I download OEPE 12.2.1.9 for Macos and I do not get a 12c selection list under Oracle Server. Just a generic Oracle WebLogic Server selection. Selecting Next only gets me Server's hostname, Server name, and Server runtime environment which only contains a "create new runtime environment". That has an "Add..." button which opens nothing and a "configure runtime environments" link which doesn't seem to do anything either.
I installed from the distribution which had not selection/configuration options.
Any ideas ? I'm needing this for upgrades.
