    I'm trying to install Lion GM over my current SL installation, but once i got past the SLA and confirm the installation disk, dialog pops out asking for admin password. Once entered, it disappears and then... nothing happens (not even error message).

    I tried all of my disks (the current one with SL, then empty partition and then even my external drive). None of them worked.

    The only error I got (only shows up in Installer Log, no pop-up window or notification whatsoever) is "IATool failed to launch". I made a quick search but not found any reference of this error anywhere.

    Anyone had this error as well? Any suggestions on how to resolve it?

    Thanks!

    Try running disk verify from Disk utility to check your disk filesytem for problems.
