Hey guys. I am having problems installing Age of Empires 3 on my late 2008 Unibody Macbook Pro (running 10.6.4). Whenever I insert the install disk, the computer tries to read the disk but ejects the disk after about ten minutes and has an error message about how it can't recognize the disk. However I tried installing it on a friend's 13 inch macbook pro, and it installed without a hitch (also running 10.6.4). I have already tried repairing disk permissions and resetting the PRAM. What should I do? Is it possible to install it on my friend's computer, and then get the install file off of his computer? If so, how would I do that? Thanks in advance.
