Installer couldn't copy the necessary support files. . .

I Know I'm a little late but I'm trying to upgrade my operating system from Mac OS X 10.4.11 (tiger) to 10.6.3 (snow leopard) and then possibly to Lion. I'm borrowing a friend's install DVD that burn from a pirated torrent. I've tried to install it multiple times but every time it gets to about 39 minutes, stays there for about 45 minutes, and then gives the message "Install Failed: Installer could not copy the necessary support files". I verified the hard drive and the install DVD and everything came out clean. Any help?
