I'm french and i'm having exact same problem.
When i launched diablo III setup, it opens a windows and the installer closed without errors.
My account is the only one on the mac, so it's admin.
I redownload many times the app, unzip it with archive utility.
I've repaired disk permissions, erase, using easyfind, all file mentioning diablo, blizzard or battle.net
As instructed by french chat assistance, i've done a reset of nvram.
Following this thread, i've changed permissions on the battle.net folder in Users/Shared
Console says :
2013-10-07 13:31:00 +0200 Diablo III Setup: Current process is NOT running as Admin: -60007
But when i launch the app, it asks me for the password, and i type it right.
What can i do ?

It looks like app is not running as admin, so asks for password.
It begins downloading and exit with an "invalid argument vector" ...
