In the dialog box there should be a little check-box to tick for "Always use this application to open this type of file".
Make sure you tick it before clicking 'OK'.

Hi Philip I really appreciate your efforts but I have done this thing many times and even by going into preference option I have set this nitro pro my default viewer but every time when I open a PDF it is still asking me the default program to open th e same kind of file.
