Can't locate previous versions of adobe apps on my Mac

I'm not a fan of the newest Premiere release, and was looking to go back to 24.5.  On my Adobe Cloud update manager, I have de-selected the "Remove Previous Versions" options, thinking this will keep the prior installed version on my system.  However, this function does not seem to be working as I cannot see a previous version on my Macbook hard drive anywhere.  I don't want to simply install an older version from the Adobe Cloud b/c it tells me my 24.5 will be removed along with all the settings - which I have spent time building.  Just wondering if anyone else is missing prior versions even when the option to remove is not selected.
