The option to install a non-DC version of Adobe Reader used to be hidden away under a menu on the DC installation screen. It seems that Adobe would really, really like you to use the DC version, because the other options have been removed.
Non DC versions are still available though from this link. The link takes you first to a forum page, then directly on to the download page, but may take some time before the download box appears.
The link was provided at response No. 14 (thegeneticbytemare) at Where can I get Acrobat Reader without DC . That response also includes links to the latest upgrade and other language versions, but note that you have to install the full version before you can install an upgrade.
