This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I have just now downloaded and installed the exam. No problems on windows 2000. Try to download it again perhaps the image was not complete(6707KB). Do not forget that you will need administrator rights to install it.
