ok here is the overview after reset several times.
i get this below screen when click on AE icon on airport with 1 in red circle.
then i get this below screen once click on older version dialogue box of "Older Version" notice the current version is 7.7.1 with check mark instead 7.7
then i get this below screen once i hit current version number and return back.
(Note: it is stated current version is now 7.7.1 above the download and install button which conflict with current version 7.7 stated next to gear icon)
if try to download i receive this message below
and if hit ok then airport utility closes automatically.
and after restarting utility i see 1 in red circle and if try to update as suggested get this screen
note the version stated here is 7.7 if try to update then back to very first pic again.
HELP!!!!!!!!!!!!!!!!!!!!!!!!
