This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori 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.
