Monkey Island Special Edition Won’t Install but unpacks?

Basically I downloaded MI:SE from here http://www.google.com?t=2982432&start=0
All the file downloaded fine, I mount the image and it loads the installation screen, everything goes fine, it loads then when it’s completed at 100% it just vanishes and the game is not on my PC at all. If I remount the image it just does the same process over and over again.
Some help would be greatly appreciated,
Thanks.
