Did you have a question? I did not see one in your post.

If what you want to do is NOT integrate Acrobat Reader in your browser,
go into Acrobat Reader's options (preferences) and disable browser
integration. That will force the browser to download the .pdf and open
in whatever is currently designated as that filetype's handler (which
would be Acrobat Reader).
