Which version of Unity 5 supports WebPlayer

Currently when I deploy to web the web player, IE and Firefox show the error "Failed to initialize player's 3D settings". I understand from viewing other posts that Unity WebPlayer does not support patched version. That said, which version should I install and how do I get it? The download page seems to only show patched version 5.2.1 which is what I currently have already. Thanks, --Mike
