First, you should download the installer from the TB site, as the installer is 'signed'. Second, if you still get the damaged disk error, see this reference.

Have downloaded it several times for the TB website & does not work. Have tried it on another Mac with no joy. The reference regarding disabling through the terminal window did not work either.

Look through this discussion as well as the comments. There is no single remedy that applies to all cases.
