deja65: Have you maybe seen the option to change to the classic installer through the more button?
laser_eyes: Just to be clear, if I click on the MORE button and select CLASSIC INSTALLERS, will the file contain the Galaxy client? Will I still need to uncheck the Galaxy client option?
The Classic Game Installers are different from the Galaxy Game Installers. The latter has Galaxy as a default option, the former doesn't have the option to install Galaxy at all.
To be certain (because, apparently, there are/have been situations where the site can fuck up and show the title "Classic Installers" while linking to the galaxy ones), look at the linked URL, if it says "galaxy_installer" (using The Witcher as an example: en1galaxy_installer1), it has Galaxy, if it only says "installer" (en1installer1) it does not contain Galaxy.
