With the settings in that screen shot calibre will use the 4.12 viewer when viewing epubs.
Rather than messing Windows Open With I prefer to use Calibre's Open With to access the 3.48 viewer as described in the link I posted in post 19.
But I've forgotten why you don't want to use the version 4 viewer, I didn't like the 4.0 viewer, which is why I hooked installed calibre into the 3.48 portable viewer. But Kovid has made a lot changes since then, so I rarely use the old one now.
