PDF Architect in web browser

I had been using PDF Architect as the default pdf view in my web browser (all of them actually).

After reinstalling windows (upgrading 7 from 32 to 64), I can't seem to make PDF Architect the default viewer for the web browswer.

I am sure I'm missing a setting somewhere.  Can someone shed some light on this for me?


My appologies… Architect was my default internet viewer while Foxit was the default viewer for the pc.
