Hi! I had the same frustrating issue. Nothing from above did work for me but it was very helpful as it was pointing me into the right solution. I found a tip regarding gatekeeper that works: it was about SystemPolicy database where gatekeeper keep its stuff and it could become corrupted. You need to restore it with default values writing this in terminal (the first command is to make a backup):
mv /var/db/SystemPolicy /var/db/SystemPolicyOLD
cp /var/db/.SystemPolicy-default /var/db/SystemPolicy
(found here http://krypted.com/mac-security/restorin...-database/ )
It should work, but if you get a "permission denied" you can do it manually by digging into the var folder at the root level in your system, var is invisible so you can use this http://blog.tice.de/?content=invisibles_engl to switch invisible items to visible and vice verse
That works for me.
mv /var/db/SystemPolicy /var/db/SystemPolicyOLD
cp /var/db/.SystemPolicy-default /var/db/SystemPolicy
