Hi, I've upgraded to snow leopard and after that I can't install a program, for example the update 10.6.1 (the download is ok, but when I click install and the license's agree it comes back to the window install).
I also can't install other programs and the lock in the security panel doesn't open (it doesn't even ask my password). Oh, and I can't go back to leopard because I made a backup only after upgraded to snow leopard.
